UNLOCK STAGE 2 FOR YOUR B8 2.0T:

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

HIGH-FLOW CATALYTIC CONVERTER (CAT):

IE’s performance downpipe includes a high-flow 200 cell per inch catalyst located as close to the turbo as possible. Our large diameter CATs allow a very large flow area and do not limit maximum power. Enjoy all the benefits and performance of a "catless" race downpipe but with reduced emissions output and no unpleasant smells.

BOLT-ON INSTALLATION:

The IE downpipe replaces the factory restrictive downpipe and midpipe exhaust tubing and connects to the OE cat-back/muffler section. Precisely manufactured mounting results in a rattle free and life long downpipe system. IE engineers utilize 3D scans of the engine bay and chassis to ensure perfect placement and an easy install.

Installation should be completed by a professional and preferably on an auto lift. CLICK HERE to view and download the install guide.

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.

Great purchase

Bought this for my a4 b8. got installed by one of IE's dealers. Paired with cold air intake and IE intercooler. Went stage 2 and felt a huge difference. Car feels and is way faster. Def worth it and exhaust crackle is cool.
