STAGE 2 & K04 TURBO READY
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.
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.
RELIABLE FLEX SECTIONS
Commonly used flex sections found on many cheaper aftermarket exhaust systems are known to fail, causing annoying leaks and performance issues. Our TIG-welded and liner reinforced flex sections are incredibly resilient to splitting or cracking for complete reliability.
