UNLOCK STAGE 2 POWER:
The IE B9 A4 & A5 Catted Downpipe is engineered to completely reduce turbocharger back pressure and increase turbo spool required for the calibrations of a stage 2 ECU tune. The combination of a performance downpipe and ECU tune together unlocks the full performance potential of your stock turbocharger and engine, delivering 97 horsepower over stock. Get ready to experience addictive power gains across the entire RPM range and an aggressive exhaust growl you are bound to love.
All IE exhaust systems are designed in-house using state of the art digital scanning for a perfect fit and manufactured from thick wall 304 stainless steel offering a lifetime of performance and fun.
The IE downpipe replaces over 6 feet of restrictive factory exhaust tubing, all the way back to the OE “Cat-Back” rear section. Sturdy fabricated mounts and precise engineering result in a rattle free and long last replacement exhaust system. 3D scanning systems were employed to ensure perfect placement both in pre and post-production phases.
