Modulated sound, comfortable ride

Modulated sound, comfortable ride

The Corsa 14540 sport catback exhaust is an X-pipe system. It features two mufflers or silencers for the driver's and the passenger's sides each. This design affords you a comfortable ride and the thrill to make a dynamic sound statement on occasion; when you step on the acceleration pedal.

Aggressive sound, drone-free experience

Aggressive sound, drone-free experience for your Audi S4

Making a (not so loud) statement on the road while enjoying a comfortable, almost sound free ride inside your car; that's your wish. Thanks to CORSA's Patented RSC (Reflective Sound Cancellation) Technology, the mufflers eliminate drone. They also shape and reduce the amount of noise emitted by your exhaust system.

Improved horsepower

Improved horsepower for your Audi S4

Mandrel-bent tubing and non-restrictive mufflers help to improve your horsepower (HP). This is because they allow unrestricted airflow and reduce backpressure. Mandrel-bending helps to maintain the same diameter through every curve. As a result, the best thing you get from the sport series is the sound. An aggressive sound during acceleration and a distinct rumble at idle.

Clean gases from your exhaust

Clean gases from your Audi S4's exhaust

The catalytic converter or cat is the most expensive part of your Corsa 14540 sport catback exhaust. It contains precious metals and ceramics that convert harmful exhaust gases into clean and safe ones. The cat helps you contribute to a safe environment while enjoying your ride.
