Why Upgrade? ✓ More Flow: Equal-length stainless steel pipes replace the restrictive factory mid section, so exhaust gas moves from the downpipes to the rear section more freely. ✓ More Sound: A louder, sharper S55 note when you are on the throttle and more character when you lift off. The sound the factory system holds back. ✓ More Power: Less restriction means the turbos spool quicker and the S55 makes more power through the rev range. ✓ Perfect Fit: Use the car selector on this page to confirm your model and year, and enter your VIN so we can double check fitment. If entered, your VIN is submitted with your order at checkout.
