What Does Cat Back Exhaust Do?

A cat back exhaust system replaces the stock exhaust system from the catalytic converter back. This can improve performance, sound, and appearance.

Performance

Reduced backpressure: A cat back exhaust system can reduce backpressure in the exhaust system. This can improve engine performance by allowing the engine to breathe more easily.
Increased horsepower and torque: The reduced backpressure can also lead to increased horsepower and torque. This can be especially noticeable on turbocharged or supercharged engines.
Improved fuel economy: A cat back exhaust system can also improve fuel economy by allowing the engine to run more efficiently.

Sound

Louder exhaust note: A cat back exhaust system will typically produce a louder exhaust note than the stock exhaust system. This can be desirable for enthusiasts who want a more aggressive sound from their car.

Customizable sound: Cat back exhaust systems are available in a variety of configurations, so you can choose the sound that you like best.

Appearance

Customizable tips: Cat back exhaust systems are available with a variety of tip styles, so you can choose the look that you want.
Increased curb appeal: A cat back exhaust system can increase the curb appeal of your car, making it more desirable to potential buyers.
