Fast Intentions is proud to present our B8 S4 Cat Back Exhaust System.

This Cat Back exhaust system is the premier upgrade for all S4 owners looking to maximize the performance from their 3.0L 24V TFSI V6 engine. Our cat back exhaust system will enhance the sound that Audi created from the factory by making it smoother, deeper, and louder.

Built as a direct OEM replacement, our exhaust system 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.
