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.

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.

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.

INSTALLATION

Install your IE midpipes without any permanent modifications or installation hassles. The installation process is straightforward and accomplished with standard hand tools.

Install time around 2-3 hours

Feels and Sounds amazing

I love the way the car now sounds and feels (with Stage 2 93 Octane Tune). Stage 1 woke up the car…Stage 2 has made the car feel like a totally different car (in a good way, obviously). I am 1000% happy with my purchases with IE. I’ve already ordered the FMIC, that I should be getting next week.
