Add horsepower and take your B8 A4, A5, or Q5 to the next level with an IE High-flow Downpipe.  The IE 3 inch stainless steel downpipe is comprised of only the best materials and quickly bolts on.  It also uses a high-flow performance catalytic converter that reduces unpleasant smells and cabin drone.

These significant power gains are added through the entire RPM band by allowing the turbocharger to flow freely through the 3" downpipe, high-flow catalytic converter, and mid-pipe.  Careful tuning of the added sound from freeing up exhaust flow rewards you with an aggressive exhaust growl every time you accelerate while minimizing cabin drone.  All IE exhaust systems are designed in-house using state of the art digital scanning for a perfect fit and manufactured from 1/16€� thick wall 304 stainless steel offering a lifetime of performance and fun.
