Welcome to the finest catback exhaust for the B7 Audi S4 on the market.

The AWE Tuning B7 S4 Performance Exhaust is a direct bolt on catback system that not only transforms the rear end of the car with it’s menacing quad tips, but also turns heads with a deep muscluar bass note.

Our exhausts have earned praise from owners and the press alike, due to their unique “Jekyll and Hyde” personality. We spend considerable time and effort during development to achieve remarkable civility when idling and at part throttle cruising, while also producing a war-cry wail when full throttle is applied. Our exhausts are like bespoke suits: each is hand made utilizing only the finest casing and packing materials, and they command respect without calling unwanted attention to themselves. Sophisticated, refined, and powerful, all at once.

Each cat back system features an H-Pipe crossover tube at the front to maximize exhaust scavenging for maximum power, as well as to take a harsh edge off the exhaust sounds. Tubing diameter for the entire system is 2.25″. This is a deep bass tone, no matter how you cut it.

The B7 S4 Performance Exhaust is available in two editions:

• The Touring Edition, which offers an incredibly sophisticated yet pronounced tone
• The Track Edition, which is not for the faint of heart – aggressive and attention grabbing

Dyno proven for legitimate power gains of14.2 HP and 14.8 FTLBS torquecorrected to the crank on our in house Mustang AWD dynamometer, the B7 S4 Performance Exhaust is a must have for any B7 enthusiast.
