Description

The Integrated Engineering IEEXCG1 is a 3-inch catted downpipe engineered to enhance performance for B8/B8.5 Audi A4, A5, and Q5 models with the 2.0T engine. This downpipe is designed to add substantial horsepower and torque when paired with a stage 2 ECU tune, offering gains of approximately 25-30 HP & FT-LB over a stage 1 tune. Constructed from 1/16" thick 304 stainless steel, this downpipe is built for longevity and reliable performance. It features a thick 16mm turbo flange to prevent warping and leaks, and an interlock core flex section that accommodates engine and chassis movement without stress. The high-flow 200 cell per inch metal matrix catalytic converter is positioned close to the turbo to efficiently reduce emissions and minimize exhaust smells and cabin drone. It replaces the majority of the factory exhaust from the turbocharger back to just before the rear axles. The included 3" to 60mm adapter easily connects to your stock exhaust system, or it can be adapted to aftermarket cat-back systems. All necessary installation hardware is included to ensure a hassle-free process. The downpipe is digitally scanned and designed in-house for an exact fit. This downpipe is compatible with the Audi A4 (2009-2015 B8/B8.5 2.0T), Audi A4 Allroad (2009-2015 B8/B8.5 2.0T), Audi A5 (2008-2015 B8/B8.5 2.0T), and Audi Q5 (2009-2017 8R 2.0T).
