Cat-back exhaust systems refer to all of the components that exhaust gasses flow through after exiting the vehicle’s catalytic converter. Typically, that includes a mid-pipe, muffler, tailpipe and tips.
What is cat-back exhaust?
Cat-back exhaust refers to any part of the exhaust system that’s behind the catalytic converter. Typically, this includes the pipe connecting the pipe from the catalytic converter to the muffler, the muffler, and the tailpipe or exhaust tips.
In the context of performance enhancements or aftermarket components, “cat-back” refers to the exhaust system section that the parts replace. Cat-back systems are available as both single- and dual-exhaust.
What is a Catback Exhaust System?
Depending on the make and model, catback exhaust systems may also include a mid-pipe, x-pipe, h-pipe, or y-pipe in addition to the standard rear pipe, resonator, and muffler. With bigger diameter pipes and smoother mandrel bends, these aftermarket cat back exhausts are made to be more freely flowing than stock items, facilitating the engine’s ability to release exhaust gases and enhancing performance.
Cat back exhaust systems increase exhaust gas flow by running pipes from the catalytic converter to the muffler and from the muffler to the exhaust tip, giving slight performance gains. However, since a catback exhaust system is installed “downstream” of the converter, your performance gains might be limited if your catalytic converter restricts gas flow.
What Does a Cat-Back Exhaust Do?
To put it simply, a catback exhaust system makes it easier for exhaust gases to leave your car and promotes more efficient engine operation. Fitting premium pipes behind the catalytic converter, a major exhaust system restriction, may seem unnecessary, but as cat back exhausts continue to gain popularity, they can have a noticeable impact on your car’s performance.
Your engine will run more quickly and efficiently if you replace the back section of your exhaust with a high-quality cat-back car performance exhaust system. This will lower the backpressure. A good cat-back exhaust system will improve the efficiency of your car’s exhaust system because of its larger diameter pipes and premium mandrel bends. And with more efficiency comes more power.
