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.

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

B8.5 A4 Stage 2

Awesome experience. Order arrived early. Down pipe and HFC are beautiful and of high quality. Upgrading from their stage 1 tune to the stage 2 tune was quick and easy. About ten minutes in my driveway. Car went from Bruce Banner, to the Hulk. Torque everywhere. Along with their CAI, the sounds the car makes is a pure symphony. They make good stuff and send it to you quickly. 100% recommend.

Great downpipe

Wasn’t sure how the sound was going to be coming out of the downpipe but it sounds clean and mean. Crackle tune sounds great too and is super fun. Highly recommend.

Quick & Easy

The HFC and downpipe install was a fun project and not too difficult even by myself. The instant power gain and enhanced sound is awesome. The quality of the parts is great too. I'm looking forward to adding my next IE component to my A4.

Audi A4 B8 Downpipe

The high flow down pipe looks and sounds amazing. It gives the car a growl in higher rpms that it was missing. Everyone asks what have you done for this thing to sound so good. The fitment was perfect and easily installed. Great product combined with the IE cold air intake for an aggressive sound. Great product.
