Overview

The Integrated Engineering IEEXCG2 is a performance downpipe system designed for Audi 3.0T Supercharged engines. Constructed from 304 stainless steel with 2.5-inch diameter tubing, these downpipes replace factory resonators to create a deeper, more assertive exhaust note. They are tig-welded for quality and durability, featuring a fully lined flex section that is supercharger approved.
Show original supplier description
The Integrated Engineering IE 3.0T Performance Downpipes are designed to enhance the exhaust note and performance of your Audi's 3.0T supercharged engine. By removing the factory resonators and replacing approximately 12 feet of tubing, these downpipes free up the exhaust system, resulting in a deeper, more aggressive sound and a potential horsepower increase of 8-12 HP. They feature a fully lined flex section that is approved for supercharged applications and will not collapse internally. The package includes all necessary hardware and clamps for a hassle-free installation, which can be performed with minimal tools. These downpipes are specifically designed for the Audi S4 (2009-2015 B8/B8.5), S5 (2013-2015+ B8.5), S5 Cabriolet (2009-2015 B8/B8.5), SQ5 (2008-2017 8R), Q5 (2008-2017 8R), and A6 (2010-2018 C7), all equipped with the 3.0T Supercharged engine. It is important to note that this product does not fit B8 S4/S5 chassis with 4.2L V8 engines. It is not C.A.R.B. compliant and is not for sale or use in California or any other jurisdiction where prohibited by law. Integrated Engineering, LLC makes no representations or warranties regarding compliance with emissions laws.
