THE WAIT is OVER for your S4 – welcome to the finest catback exhaust for the B7 Audi S4 on the market.

Built in AWE’s 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.

A noticeable, but not over the top, sound tone flows through T304 mandrel bent stainless steel piping offering perfect fitment and a lifetime of enjoyment.

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.

Fits both Tiptronic and manual transmission cars.

Dyno proven for legitimate power gains of 14.2 HP and 14.8 FTLBS 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 AWE’s  High-Flow Downpipe system section for more details.

You can now get this awesome exhaust system, as well as the downpipes, from BRracing, and we can do the full installation, at prices that can’t be beat by anyone.  Unlease your beast, and let it breathe….get the a performance solution that not only looks great, sounds great, but moves.
