Fits 2006-08 Audi S4.
50 state smog legal system. No check engine light guarantee.
Increased horsepower, torque, and throttle response while reducing weight. Replace your restrictive factory system with the amazing growl of AWE tuning.
The AWE touring edition exhaust systems are hand-built with mandrel bent, stainless steel tubing, and offer perfect tone and decibel levels for spirited street use. Even your mother-in-law will love it.
Kits come with straight-thru, front and rear resonators that fine tune the sound within an enjoyable frequency range without restricting exhaust flow. These resonators also eliminate any annoying drone while cruising. Drone is cancelled by way of AWE's 180 degree noise cancelling technology.
For further tone balance and great sound, an X-pipe is used to blend exhaust flow for even scavenging.
Mounting flanges are measured and sized to exactly match all port openings to eliminate any chance of air leaks.
Internally hand-finished butt welds are used at every junction.
3.5" (88.9mm) double-walled tips that won't discolor, even with harsh use. Tips are adjustable so you can mount them within the bumper just the way you like. Tuck them all the way back, or let them show proudly past the bumper.
Tips are engraved with the AWE tuning logo.
AWE tuning promises your system will fit and function perfectly, and offers a lifetime guarantee for any material defects. A 30-day fitment guarantee is also offered. If a qualified installer has any issues installing your AWE system, it can be returned within 30 days for a full refund.
