Fast Intentions is proud to present our B7 S4 Catted Downpipes.
These down pipes are the premier upgrade for all S4 owners looking to maximize the performance from their 4.2L FSI V8 engine. Our down pipes effectively increase low end torque and maximize power throughout the entire RPM range. Your overall exhaust volume will increase, while creating a deeper and smoother tone commonly associated with exotic European sports cars.
Built as a direct OEM replacement, down pipes are designed to be an addition to your cat back exhaust system. We maximize performance by using a less restrictive catalytic converter and increasing tubing diameter to free up back pressure.
PRODUCT INFO
- Direct OEM replacement: no cutting or welding required.
- 2.5" T-304 mandrel bent stainless steel tubing.
- The catalytic converter is a 300-cell metallic core incased within a spun stainless-steel shell.

- J-Bend style O2 sensor anti fouler to ensure CEL (Check Engine Light) stays off.
