What Is Cat Back Exhaust?

A cat back exhaust system is a modification made to a vehicle’s exhaust system, specifically from the catalytic converter to the rear of the vehicle. It is designed to improve the performance, sound, and overall efficiency of the vehicle.

The term “cat back” refers to the section of the exhaust system that is replaced or modified. The catalytic converter, located near the front of the vehicle, remains untouched. The modification begins from the catalytic converter and extends to the rear of the vehicle, typically ending with a new muffler or a set of performance mufflers.

A cat back exhaust system aims to increase the flow of exhaust gases, reduce back pressure, and enhance the overall performance of the vehicle. By replacing the restrictive factory exhaust system with a more efficient one, the engine can breathe better, resulting in improved horsepower, torque, and fuel efficiency.
