AWE Tuning - Audi B6 S4 Touring Edition Exhaust with Silver Tips

Dyno verified gain of 14.2 HP and 14.8 FTLBS TORQUE corrected to the crank.

Developed in-house on our AWD dynamometer, with a critical ear lent to sound volume and tone character, we guarantee the most powerful exhaust system yet for this great car. Featuring our distinctive double walled taper tips in a 3.5" (90mm) diameter, this system looks fantastic on the car.

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.

We have two versions of this exhaust to appeal to the various tastes in sound volume out there. Like it quiet, barely louder than stock? No problem, choose our resonated version. Like to announce your V8 presence with a shout during acceleration? Got you covered with our non-resonated version.

If you like a loud, raucous V8 sound, order the NON-RESONATED Track version of our exhaust.

If you like the powerful sound of a V8, but need a civil volume, order the RESONATED Touring version.

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.

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.
