What is a cat-back exhaust system?

Buying a cat-back exhaust system can be intimidating, from determining your ultimate target sound or power boost to determining the type of exhaust you need to achieve your goals. This article will focus on Catback exhaust and explain what it means, what it contains, and why you want it in your truck.


Catback exhaust refers to the “cat” or “behind” of the catalytic converter. This refers to the component that runs from the rear outlet of the catalytic converter to the end of the exhaust pipe.

What Does Cat-back Exhaust Gas Contain?

The Catback’s exhaust system includes the pipe from the catalytic converter to the muffler, the muffler itself, the pipe from the muffler to the exhaust tip, and the exhaust tip itself. Some Catback exhaust systems do not include a muffler as they have a muffler removal feature. This is common in vehicles designed primarily for off-road use. It’s not the standard for cars you drive every day, and it’s illegal in some states.

Why is my car’s exhaust system important?

Put simply, the exhaust gas of a car is a conduit used to divert harmful gases from combustion inside the engine. It plays an important role in removing toxic compounds from the passenger compartment and harmful gases from the engine that can corrode the vehicle from the interior.

This is why using the right parts is so important to vehicle maintenance. For the exhaust system to perform at its best, it is very important to use the right materials, such as purchasing stainless steel and aluminized steel parts that are not easily corroded by gases.

Many detailed automotive studies have shown that the freer the exhaust flow, the better for the vehicle. The intermediate exhaust systems of most passenger cars are designed to meet minimum automotive industry standards and are focused on noise reduction rather than maximum performance. As a result, many OEM systems are quite limited. Meanwhile, in the world of high-performance automobiles, most mechanics recommend adding a larger exhaust pipe and free-flow muffler when tuning the engine and adding power, so that you can fully benefit from all the parts.

Why Cat-Back Exhaust Tailpipes Matter

For many vehicle owners, Catback tailpipes are one of the first things they install. Depending on the engine, the exhaust can change from an unexplained sound to a sound that is too deep and hoarse. However, the number one reason many people buy an exhaust system is noise, but there are more benefits than noise.

A note on aggressive exhaust: Most Catback exhaust systems include a low-material muffler that reduces noise. And with their design, you get a deeper, louder sound. Improved Exhaust

Gas Flow: The larger diameter of the Catback exhaust pipe and less restrictive resonators and mufflers allow the exhaust to flow more freely.

Reduced Weight: Every car is different, but the OEM SRT Challenger Catback exhaust for example weighs roughly 74 pounds. The Magnaflow replacement weighs approximately 44 pounds.

Increased Productivity: The weight-to-weight ratio is improved thanks to the reduced weight.

Why Catback Exhaust Systems Are Worth

Yes, they’re worth it. There are many Catback exhaust system options on the market today. And finding the best of them can seem overwhelming. The most popular products are Borla, Corsa, Flowmaster, Gibson and Magnaflow. But take the time to fit your riding style.

If you need a reason to convince your loved one that an exhaust pipe is valuable, we’re here to help. Ultimately, a better reverse coil exhaust system will help improve vehicle performance by removing exhaust gases from the engine more efficiently. Otherwise, fuel consumption, power and speed may be reduced. So this is a good investment. It’s a pun.
