Equipping your Audi B8 EA888 Gen 2 TSI 2.0T engine with an IE catted downpipe delivers additional horsepower, torque, and responsiveness when paired with a required stage 2 or K04 turbo ECU tune. These significant power gains are added throughout the entire RPM band by allowing the turbocharger to flow freely through the 3" downpipe, high-flow catalytic converter, and mid-pipe.
PERFECT FIT
IE downpipes for the Audi 2.0T TSI 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.
HIGH-FLOW RACE CAT
IE's performance downpipe includes a high-flow 200 cell per-inch catalyst located close to the turbo. Our large diameter CAT allows an extensive flow area and does not limit maximum power. Enjoy all the benefits and performance of a "catless" race downpipe with reduced emissions output and no unpleasant smells.
