The wait is over - welcome to the finest catback exhaust for the B7 Audi S4 on the market.
Built in our state of the art manufacturing plant, the B7 S4 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.
AWE exhausts have earned praise from owners and the press alike, due to their unique "Jekyll and Hyde" personality. AWE 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. AWE 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.
Dyno proven for legitimate power gains of 14.2 HP and 14.8 FT LBS TORQUE corrected to the crank on a Mustang AWD dynamometer, the B7 S4 exhaust is a must have for any enthusiast.
A natural progression from a cat back exhaust system is the installation of downpipes to really help the engine breathe. See our High-Flow Downpipe system section for more details.
