Welcome to the finest catback exhaust for the B7 Audi S4 on the market.
The B7 S4 AWE Touring Edition Exhaust is a direct bolt-on catback system that transforms the rear end of the car with its menacing quad tips and turns heads with a deep muscular bass note.
Each catback system features an H-Pipe crossover tube at the front to maximize exhaust scavenging for maximum power and to take a harsh edge off the exhaust sounds.
The tubing diameter for the entire system is 2.25 inches.
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 lb-ft torque corrected to the crank on our in-house Mustang AWD dynamometer, the B7 S4 Performance Exhaust is a must-have for any B7 enthusiast.
The ultimate exhaust solution for the 3.0T features a deep, sophisticated V8 tone with dyno-verified gains of 11 hp and 12 lb-ft of torque at the wheels.
Aggressive quad tip design is available with Chrome Silver or Diamond Black tips.
No Check Engine Light is guaranteed with perfect fitment, which is also guaranteed.
Features AWE’s Lifetime Warranty.
