AWE Tuning 3010-43030 13-17 Audi S5 Coupe 3.0 AWD Exhaust System

Welcome to the finest catback exhaust for the B7 Audi S4 on the market. The AWE Touring Edition Exhaust for the B7 S4 is a direct bolt on catback system that not only transforms the rear end of the car with its menacing quad tips, but also turns heads with a deep muscluar bass note. 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 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.
