Direct-Fit versus universal-fit catalytic Converter? (Correct answer)

Direct-fit catalytic converters exactly match the design of the OEM part. Whereas, universal-fit converters come in a specific design and can be made compatible with a number of vehicles with minor alterations.

Is a universal catalytic converter good?

Universal catalytic converters are a great option for those needing to replace a defective catalytic converter on their vehicle. This is because universal catalytic converters can be made to fit many more vehicles than the one that came with your new car and are often less expensive.

Can you use a universal catalytic converter on any car?

As the name implies, universal catalytic converters can be installed in almost any vehicle, as long as the diameters of the inlet and outlet tubes are the same on the converter and the exhaust system, and it is the correct converter for the particular vehicle and the state it will be registered in.

Can you install a universal catalytic converter?

A universal converter is still specifically made for that class of vehicles. You cannot install a catalytic converter that is not made specifically for that car, be it universal or direct fit.

How long does a universal catalytic converter last?

The truth is, on modern vehicles, the catalytic converter should last the life of the car or truck, given an “average” life of about 100,000 miles (160,934 kilometers). Good thing, too, because this auto part uses rare, precious and therefore expensive metals such as gold, palladium or rhodium.

What is the difference between an OEM and aftermarket catalytic converter?

OEM Catalytic Converters are designed to last the entire lifetime of your car if handled adequately. Aftermarket Catalytic Converters have no responsibility to survive that long, so they are made using cheaper materials.

How much does it cost to install a universal catalytic converter?

Did You Know? Catalytic converter replacement isn’t cheap. For most vehicles, the average cost of a catalytic converter repair is between $945 and $2475 including parts and labor. The catalytic converter cost itself can be up to $2250 of that.

What cars have the most valuable catalytic converters to scrap?

Which Catalytic Converters Are The Most Expensive? According to data from 2020, the most expensive catalytic converter belonged to the Ferrari F430, with a mind-popping $3,770.00 price tag.

Why are CA catalytic converters so expensive?

Your catalytic converter is expensive because it needs rhodium to reduce smog levels. Rhodium, at its current value, is extremely expensive which makes using it in a catalytic converter expensive. To make up for their cost, manufacturers have to increase the price of the catalytic converter.

Can I replace my catalytic converter with a straight pipe?

Originally Answered: Can you replace a catalytic converter with a straight pipe? Yes. However, it will then fail any safety inspection. If your locale does not require testing for exhaust emissions, you should be OK.

Can you install a catalytic converter without welding?

It is okay to replace a catalytic converter with using clamps and sleeves. It is best to have one welded on but if you cannot have it welded on, you can clamp it on with no leaks.

Can I pass emissions with aftermarket catalytic converter?

Yes. If it is similar in specs or from the same vehicle manufacturer after market. Ideally, vehicle emissions would be more clean with a newly fitted catalytic converter.

What are the signs of a bad catalytic converter?

Among the symptoms of a bad catalytic converter are:

  • Sluggish engine performance.
  • Reduced acceleration.
  • Dark exhaust smoke.
  • The smell of sulfur or rotten eggs from the exhaust.
  • Excessive heat under the vehicle.

What happens to a car when the catalytic converter goes bad?

A convert can often last for 10 years or more, but they can become contaminated, clogged, overheated or physically damaged — leading to sluggish engine performance, cause a check engine light and, eventually, engine shutdown.

What causes bad catalytic converter?

Possible causes are an improper fuel mixture, incorrect timing, bad spark plugs, a malfunctioning oxygen sensor, sticking float, defective fuel injector or a faulty check valve. Oxygen Sensor Not Functioning Properly. Too rich and the catalyst can melt down from fuel burning inside the converter.

Catalytic Converter: Direct Fit vs Universal Fit

It is commonly known that car replacement components are available in both original equipment manufacturer (OEM) and aftermarket configurations. In most cases, aftermarket components are offered in either a direct-fit or a universal configuration. This page describes replacement catalytic converters that are designed to fit either a direct-fit or a universal-fit vehicle. Direct-fit catalytic converters are designed to be a perfect match for the original equipment manufacturer’s part. Universal-fit converters, on the other hand, are designed in a certain way and may be made compatible with a wide range of cars with simple modifications.

They are designed and built to meet the unique requirements and limits of the vehicle in which they are to be placed.

It is common for direct-fit converters to be more expensive than universal cat converters.

If your vehicle still has a factory-installed or OEM-styled exhaust system, we recommend that you install a direct-fit catalytic converter to reduce emissions.

  1. Most of the time, these converters are less expensive than direct-fit converters.
  2. For universal-fit converters to work, the relevant components and vehicle-specific parts must be acquired separately and installed together once they have been received.
  3. It also entails a significant amount of physical labor and effort.
  4. Because of the way some vehicles are designed, it might be difficult to install a universal converter in them at times.
  5. Alternatively, you can consult a mechanic to determine if you should get a direct-fit converter or a universal-fit converter.
  6. While you’re having the catalytic converter changed, have the oxygen sensors checked and replaced if they’re not working properly.
  7. Catalytic Converter Failure: What to Look for and What to Do carries a large selection of universal-fit and direct-fit catalytic converters for a variety of vehicles.

Two Flavours of Catalytic Converters

Having grown up during the introduction of catalytic converters, I recall the skepticism that many drivers of high-performance automobiles held towards these emission-reducing devices. No one liked them, and the vast majority, if not all, of the population believed that all they did was deprive automobiles of their power. The fact that many DIYers with muscle cars would swap out the catalytic converter for a straight pipe as soon as they drove their new vehicle off the dealer’s lot was widely known in the industry at the time.

  • While catalytic converter issues are not widespread, they can arise from time to time, and manufacturers provide replacement parts in two different product categories.
  • According to Pat Haynes of Walker Exhaust, a branch of Tenneco, “the direct fit requires no modification other than unbolting it at the service joint and rebolting it in.” All that is included in the universal fit catalytic converter is the converter body itself.
  • “The universal converter is just that: a converter, and you must load everything else onto it yourself.
  • In order to install the universal fit, Joe Mercanti, regional manager for Bosal Canada Inc.
  • “What you’ll find these days is that the converter is manufactured expressly for the car, rather than having a universal design.
  • a universal converter It is not as straightforward as just installing direct fit converters.
  • “You still have to deal with the problem that caused the converter to fail in the first place,” says the technician.

“They fix the problem location, and then (he) determines whether to install a direct fit conversion or a universal converter.” If he chooses the direct fit option, he just purchases the unit and then unbolts the old unit before bolting in the new one.

The cost is a consideration.

When you go to a universal fit, you must cut the pipes and weld them together.

In addition, the service station must be equipped with all of the necessary equipment to do its duties properly.

Allow the client to make the final decision.

Please keep in mind that the performance and characteristics of a direct fit and universal fit catalytic converter are exactly the same as each other.

In contrast to someone manufacturing it in their shop – cutting and welding tubing – “the distinction is that we manufacture the entire direct fit assembly.” The converters are custom-built for each individual car.

It is not possible to install a catalytic converter that is not particularly designed for that vehicle, whether it is universal or direct fit.

“It varies from job to job,” Smith explained.

It is enough unpleasant that you would prefer a straight fit.

It is less time-consuming and labor-intensive than other methods.

It is a simple task to do.

According to Walker’s Haynes, “there is a more sophisticated and narrower region to operate in – where converters are occasionally fitted into new automobiles.” “Typically, in modern vehicles, the catalytic converters are located closer to the engine, which means there is less space to work in.” Due to the difficulties of installation, Bosal does not manufacture universal fit catalytic converters.

According to Mercanti, mounting universal fit catalytic converters is not as simple as it used to be because of the location of the converters, the configuration in which they are installed, and the access that a technician has to the converters.

Because of the intricacy, the industry is evolving towards more direct fit catalytic converters.” According to Haynes, the universal fit had an 82 percent share of the replacement catalytic converter market in 2006, but by 2010 it had decreased to 57 percent, representing a 15 percent loss in market share in just four years.

As he continues, “general repair shops will tend to choose direct fit converters since they often do not have the facilities to perform all of the necessary cutting and welding, as well as sizing the converter to suit the vehicle.” Direct-fit catalytic converters provide a major benefit to a regular repair shop versus a specialist “muffler shop” in terms of labor savings.

Alternatively, a comprehensive repair facility with all of the necessary scan tools and equipment may perform a thorough diagnostic on the vehicle to discover what exactly went wrong, address the issue that caused the converter failure, and then decide which sort of converter is required.”

The Different Types of Catalytic Converters

Automobile manufacturers were charged with decreasing tailpipe emissions from the cars they manufacture as a result of the Clean Air Act of 1970. The catalytic converter, often known as a “converter” or just “cat” for short, has long been recognized as an essential component in meeting emissions laws. A catalytic converter is a device that converts hazardous pollutants into less damaging emissions through chemical reactions. Exhaust gases passed through a substrate that was exposed to heavy metals (such as platinum and palladium) as a means of triggering chemical reactions in the early stages of catalytic converter development.

Along with the two oxidation catalysts, they incorporate a third chemical process: a reduction catalyst that transforms NOx into N2 (nitrogen) and O2 (oxygen) (oxygen).

What is a Direct-Fit Catalytic Converter?

Direct-fit catalytic converters are those that include fittings on either end of the device that allow them to be bolted or screwed directly into the vehicle’s exhaust system. In most cases, just simple hand tools are necessary to install them, and they require little to no exhaust construction (such as cutting, welding, or articulating). Direct-fit converters are often more expensive than universal converters since they are custom-designed to meet the exact specifications of each year, make, and model of car they are installed in.


  • There is little to no exhaust manufacturing required
  • The system is simple to install. Design that attaches to the vehicle
  • Vehicle Specific

What is a Universal Catalytic Converter?

It is true that universal catalytic converters can be installed in almost any vehicle, provided that the inlet and outlet tubes on the converter and the exhaust system are the same diameters, and that the converter is appropriate for the vehicle in question and for the state in which it will be registered. (For further information on where to get a catalytic converter, please see this page.)


  • Affordable
  • Universal fit
  • Requires expert installation
  • Requires no special tools

What is a Manifold Catalytic Converter?

Like direct-fit converters, which attach to the exhaust line of a vehicle directly, manifold catalytic converters are incorporated into the exhaust manifold of a vehicle, which is a component responsible for collecting exhaust fumes from many cylinder engines and directing them into a single pipe. Generally speaking, manifold converters are more expensive than direct-fit or universal converters, owing to the fact that they are designed specifically for certain vehicle types and are fitted to them.

(See illustration)


  • Designfitting that is specialized
  • Installation that necessitates the use of a professional or extensive mechanical understanding

What is a CARB Compliant Catalytic Converter?

Vehicles registered and operated in California must comply with the California Air Resources Board (CARBown )’s set of environmental regulations; however, these restrictions do not apply to vehicles registered and operated outside of California. CARB compliant catalytic converters must comply with the CARB’s own set of environmental regulations. The CARB Compliant rule, which was passed in 2009, mandates that all aftermarket catalytic converters supplied in California must meet or exceed low emission vehicle (LEV) criteria.

The California Air Resources Board (CARB) is best recognized for developing creative techniques to complying with air pollution standards and regulations. Despite the fact that California’s CARB laws are now in effect, many other states are adopting the same framework as California.

What are Federal/ EPA compliant Catalytic Converters?

It is possible to obtain a Federal Environmental Protection Agency-compliant catalytic converter for your car if it is registered and used outside of California.

  1. The Environmental Protection Agency (EPA) certifies heavy metal catalytic converters for use in non-California (49-state) automobiles, but not for use in California-registered vehicles
  2. HM converters are not approved by CARB. Catalytic converters of OEM quality: OEM-grade converters are compliant with both EPA and CARB regulations. If a vehicle is registered in California, however, only CARB-approved converters can be used
  3. Otherwise, no converters are allowed.

Refer to the emissions tag in your vehicle’s engine compartment if you’re not sure which one you’ll need. It should be situated under the hood, under the radiator core support, or on one of the strut towers. Do you require a replacement catalytic converter? Please contact us at 1-800-990-0905 and we will be pleased to assist you.


You’ve got some competition when it comes to tough pollution regulations, California. New York, which had already embraced California’s low-emission vehicle (LEV) rules in 1990, has now adopted California’s harsher criteria for aftermarket catalytic converters, which are more stringent than the state’s previous requirements. The New York Department of Environmental Conservation has published a fact sheet that contains detailed information on the requirements and standards. We at MagnaFlow have used this opportunity to educate you on how to select the most appropriatecatalytic converter for your on-road vehicle or pickup truck.

Start by restricting your search for the best catalytic converter for your vehicle’s year, make, and model.

You may look for your converter on the MagnaFlow website using the year/make/model search option, or you can shop for your converter on websites such as that allow you to search by year/make/model.

It is commonly found in one of two locations in the engine compartment, as indicated below, according to MagnaFlow.

  • The use of Heavy Metal Grade OBDII is restricted to cars that meet the requirements of the EPA (Environmental Protection Agency) for Tier O and Tier 1 emissions. OEM Grade OBDII: For cars that meet or exceed California (CARB) TLEV, LEV, ULEV, SULEV, or Federal (EPA) NLEV emissions standards, OEM Grade OBDII is recommended. Vehicles that comply with the new New York State standards for aftermarket catalytic converters are now included in this category.

Always remember that these are simply MagnaFlow suggestions, and that they do not relieve the technician of the obligation of doing a full diagnosis and installing the proper catalytic converter for the application. MagnaFlow catalytic converters are available in three distinct configurations to fulfill the requirements of your local emissions regulations: Loads that are considered standard Pre-OBDII conversion device Loads that are considered standard Pre-OBDII: This OBDI-compliant converter, which is designed to fulfill EPA emissions regulations, is available in a universal-fit format and is suitable for both gasoline and diesel engines.

  • In addition to the typical clam shell shape, MagnaFlow also manufactures this catalytic converter in a more compact spun-body configuration.
  • OBDII for Heavy Metals: They have been improved to meet or surpass EPA emissions regulations and to meet or exceed the 49-state fitting and performance criteria of early-OBDII applications.
  • When used in conjunction with early-OBDII catalyst efficiency monitoring and tailpipe emissions, these converters offer the requisite precious metal loading.
  • Once you’ve determined the grade of your converter, you may choose between a direct-fit and a universal-fit design.
  • A universal-fit catalytic converter, on the other hand, may necessitate the use of cutting, welding, or construction.
  • Essentially, the spun-body design is a one-piece design, in which the converter body is formed from a single piece of tubing and then spun into the final converter shape.
  • Emissions requirements are not going away, whether you like them or not.
  • David Fuller is the author of this piece.
  • While working in the auto sector for over two decades, he has covered several races, exhibits, and industry events as well as written pieces for a number of journals and newspapers.

His work with mainstream and trade media has also included a wide range of editorial assignments in collaboration with those publications. In 2012, he collaborated on the creation of OnAllCylinders, where he likes writing about all aspects of hot rodding and racing.

Is a universal catalytic converter good?

If your vehicle still has a factory-installed or OEM-styled exhaust system, we recommend that you install a direct-fitcatalytic converter to reduce emissions. There are no modifications required to the system, and universalconverters are designed to work with a wide range of applications. Most of the time, these converters are less expensive than direct-fit converters. On current automobiles, the catalytic converter should last the lifetime of the vehicle, assuming a “average” life of around 100,000 miles (160,934 kilometers).

One can also wonder if it is possible to employ an aftermarket catalytic converter.

Any vehicle operating in the state must be equipped with aftermarket replacement converters that are CARB-compliant.

The following are our suggestions for the four best catalytic converters currently available on the market:

  • In conclusion, the Magnaflow 99205HM Universal Catalytic Converter, the Walker 16370 Direct Fit Catalytic Converter, the Flowmaster 2230130 Series 3′′ Inlet/Outlet Universal Catalytic Converter, and the Walker 16468 Ultra Direct Fit Catalytic Converter are all excellent choices.

OEM vs Aftermarket Catalytic Converters…Which Is the Best Option?

The first thing you might have asked yourself if you were told that your car’s catalytic converter needed replacing was, “What exactly is a catalytic converter?” You may have followed up by asking, “How much is this going to cost?” after learning about the significance of this crucial exhaust system component. If you have not yet had this discussion with your service provider, please continue reading so that you will be better prepared in the event that you are given this diagnosis in the future.

The Catalytic Converter: Why It’s So Important

When you take your vehicle for an emissions test, the catalytic converter in your vehicle plays a significant part in determining whether or not your vehicle passes. Nitrous oxide is produced by the engine of an automobile, and this adds to air pollution. The catalytic converter is responsible for converting nitrous oxide into harmless nitrogen and oxygen in the exhaust. It also turns harmful carbon monoxide into harmless carbon dioxide, as well as useless hydrocarbons into harmless carbon dioxide and water, as previously stated.

A catalytic converter is intended to last for the lifetime of the vehicle, but it may be necessary to replace one if the unit is damaged or fails as a result of incorrect or insufficient maintenance.

OEM vs. Aftermarket Catalytic Converters: The Basics

When it comes to replacing a catalytic converter, you have the option of using an original equipment manufacturer (OEM) or an aftermarket part, just like you would with most other automobile parts. There are advantages and disadvantages to both options. When faced with costly auto repairs, it is almost always possible to save money by using aftermarket parts instead of OEM parts. A catalytic converter is a high-priced component that must be replaced. However, the cost of OEM and aftermarket components varies depending on the quality and where you buy them.

  1. On the other hand, the adage “you get what you pay for” is typically true in most instances.
  2. When you get your car’s emissions tested and your vehicle has an OEM catalytic converter, you can be certain that your vehicle will pass the inspection.
  3. The quality of aftermarket parts varies greatly.
  4. In most cases, a professional repair shop would push you to find a means to afford a high-end original equipment manufacturer component.
  5. It’s typically not a good idea to go with the cheapest choice because you’ll almost certainly end up having to replace it later.

There are a variety of factors contributing to the price difference between aftermarket and OEM products. One major reason is that aftermarket manufacturers cut corners on precious metals that are both durable and expensive, such as platinum, palladium, and gold.

Overall, Aftermarket Catalytic Converters Perform the Same Functions as OEM Converters

In addition to the PO420 check-engine diagnostic code for catalytic converter efficiency, there are further safety measures to verify that the catalytic converter is performing as intended. This code will glow on your dashboard if your converter is not functioning properly or is not running as effectively as it should be. If you install an aftermarket replacement catalytic converter in your vehicle, your vehicle will generate the same error number as if you used an OEM part. A high-quality aftermarket converter should function well.

We encourage you to contact us if your exhaust system has failed an emissions test or if you have seen a PO420 code on your dashboard.

As a company, our objective is to deliver great service while using high-quality components to ensure that you only have to repair your catalytic converter one time.

How to install a universal catalytic converter

When growing concern about air pollution became a global issue, the catalytic converter became a required component in automobiles to reduce pollutants. Because it converts 90% of hazardous emissions into less toxic gases, it contributes to the reduction of airborne pollutants in the atmosphere. It also helps to enhance the overall performance of your vehicle by immediately enhancing its general health, efficiency, and cleanliness by producing less emissions when properly maintained. By following the manufacturer’s suggested maintenance plan for your vehicle, you can avoid the need for repair or replacement of your catalytic converter.

  • It is possible to increase the lifespan of your catalytic converter by more than ten years if you keep them in good condition.
  • If you decide to remove your catalytic converter, you will need to install a replacement unit.
  • Yes, your car will still be able to operate, but you will be subjected to severe fines if the authorities discover that you do not have a catalytic converter installed in it.
  • If you are able to get a new catalytic converter installed, you will notice an increase in horsepower and torque since there will be less backpressure.


Universal Catalytic Converters may necessitate changes to your vehicle’s combustion system, but they are intended to accommodate a wide range of automobiles on the market. They may be available in certain designs and may be made compatible with these automobile manufacturers by making simple modifications to their design. This is a suggested alternative if your exhaust system is already equipped with a universal converter, or if you are just looking for the most cost-effective converter that will fit within your financial constraints.

As a result, it is preferable to select a converter that is compatible with your vehicle’s combustion system as well as having other characteristics that may impact the installation.


In order to perform the installation of the universal catalytic converter yourself, you will need the following tools, equipment, and supplies that will cost you approximately $20 (excluding the catalytic converter): If you want to save money, you can purchase the following items from a local auto parts store for under $20:

  • In addition to the new universal catalytic converter, a ratchet and socket set, an oxygen sensor socket, penetrating oil, and jack stands are also included.


  • Please make certain that you get the suitable converter for your car according on the model, make, and year that you acquired your vehicle. Purchase a new vehicle rather than a reconditioned one. Prepare to put all four of your wheels on jack stands. Prior to commencing the wrenching process, let your vehicle to drop down in temperature and allow the air to flow. Go to the old catalytic converter and turn it off. Remove the oxygen sensor and its connections by using the oxygen sensor socket that has been designed specifically for this purpose. Make use of your ratchet to loosen the bolts at the flanges. Begin from the rear of the room and work your way forward. Don’t try to push it since it could be too little. Spray the metal with penetrating oil first and allow it to sit for a few minutes to allow the metal to soften a little. Give it another shot
  • It’s time to replace out the old converter for a newer model. Replace the oxygen sensor as well as the fittings that go with it. Simply ensure that the new universal catalytic converter is securely fastened in its position. You’re ready to jump in the automobile and take it for a spin
  • The replacement isn’t too tough to do. It will only be rusted bolts or welded components that will make the process more difficult or require you to spend more time completing the task. If you’re doing it yourself, make sure the check engine light is turned off when you’re finished with the replacement procedure first. Now it’s time to start your automobile. If the check engine light is still illuminated, it might indicate a damaged catalytic converter or a malfunctioning oxygen sensor.
  • You may also utilize a diagnostic scan tool to assess whether or not you need to return to the work you’ve done previously.


Parts for catalytic converters that are aftermarket are available in two varieties: direct fit and universal catalytic converters.


Direct-fit catalytic converters are designed to be a perfect match for the original equipment manufacturer (OEM) portion of the vehicle. They are meant to be installed into the vehicle without the need for any further modifications to the mount area or the exhaust system. Direct fit is a type of fabrication that takes use of the characteristics and limits that are specific to the vehicle into which they will be placed. They are acquired in conjunction with the necessary accessories, such as pipe extensions, flanges, and brackets.

The ideal candidates are DIY technicians who are familiar with the process of replacing catalytic converters and who can finish the work without the need for special tools that are often only available at auto repair businesses.


They are sent to you in a predetermined design and are already compatible with a variety of car makes and models. It is just necessary to make a few small adjustments. In most cases, they are less expensive than direct fit converters. However, their DIY installation necessitates the use of additional equipment. This requires cutting the pipes to their proper lengths and then reinstalling them in the new converter. In addition, you must acquire individually connected components as well as vehicle-specific parts, and then put them all together yourself.

Simply be sure that the catalytic converter you choose is compliant with the state regulations in which it will be installed, regardless of whether it is a universal or direct fit.


As a skilled technician, I understand your motivations as a car owner for attempting to change your catalytic converter yourself. As a car enthusiast, you would want to gain a feel for what’s going on under the hood or underneath your vehicle and perform all of the replacement and tightening work yourself, because, after all, vehicles are your passion. But first, a word of caution. As an amateur mechanic, I would recommend that you utilize a direct fit universal catalytic converter when changing your universal catalytic converter if you do not have all of the essential equipment on hand while doing the replacement.

Using a direct fit is similar to using a Lego or a toy vehicle construction kit in that everything is measured to ensure that everything fits properly and snuggly to all of the components. This is my point of view.


It is required to have a catalytic converter installed in the rear of your vehicle at all times, whether it is a direct fit or a universal converter. When it comes to DIY, the ideal attitude is to ask yourself whether you are equipped with the appropriate equipment and with the necessary mindset if you choose the Universal conversion option. If you answered yes, continue. If this is not possible, go for the considerably simpler and more easy direct fit converter.

Best Universal Catalytic Converter Review

Modern vehicles are equipped with catalytic converters, which are devices that are inserted into the exhaust system in order to minimize the level of pollution in the exhaust gas produced by the vehicle. It is constructed of materials that enable chemical reactions, converting pollutants such as carbon monoxide generated by the exhaust system into carbon dioxide and water before they are discharged into the atmosphere, as opposed to conventional construction. In recent years, it has become an obligatory component of a car exhaust system, with both state and federal governments making it a requirement for all vehicles.

Install Magnaflow Universal Catalytic Converter

My truck was displaying signs of a faulty catalytic converter at the time. Due to its age, it was a fair bet that changing the catalytic converter would resolve the issues. Fortunately, replacing the catalytic converter with a new Magnaflow converter is a very inexpensive repair for an old vehicle. After I switched out the cat, I noticed a substantial increase in my overall power. The truck in this video is a 1991 Chevrolet C1500 Scottsdale, and the universal fit catalytic converter will work on virtually any vehicle that has a downstream catalytic converter in the exhaust system.

In addition to a Sawzall or angle grinder with a metal blade and some wrenches for the clamps, you’ll need a few more tools.

Some universal catalytic converter install notes.
