Audi B7 S4 Exhaust

Fast Intentions is proud to present our Audi B7 S4 Exhaust System.

This Cat Back exhaust system is the premier upgrade for all S4 owners looking to maximize the performance from their 4.2L FSI V8 engine. Our Audi B7 S4 Exhaust will enhance the sound that Audi created from the factory by making it smoother, deeper, and louder.

Built as a direct OEM replacement, our Audi B7 S4 Exhaust is easy to install with simple hand tools; no cutting or welding required. Our X Pipe is designed to increase low end torque and maximize power throughout the entire RPM band. The exhaust system is unobtrusive at idle and cruising speeds; but comes to life at wide open throttle. Our exhaust system gives your Audi S4 that exotic sound associated with European sports cars. With the addition of our exhaust system, you will improve the aesthetics of your vehicle with its sporty and classy appearance.
