Equipping your B8 A4 or A5 2.0T engine with an IE catted downpipe delivers additional horsepower, torque, and responsiveness when paired with a matching Stage 2 ECU tune. 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.
