Overview

The Integrated Engineering IEEXCI3 is a performance downpipe designed to replace the restrictive factory exhaust tubing. It features 76mm (3-inch) 304 stainless steel piping and a high-flow 200-cell catalytic converter. The downpipe is TIG welded for durability and includes an OEM-style flex section.

This downpipe is intended to reduce back pressure, improve exhaust flow, and reduce turbo lag, especially when upgrading to Stage 2 software. It is manufactured from 304 stainless steel for longevity.
Show original supplier description
The Integrated Engineering IEEXCI3 performance downpipe is engineered to unlock Stage 2 power for compatible VW and Audi vehicles. It replaces over six feet of restrictive factory exhaust tubing with 76mm (3 inch) 304 stainless steel tubing, designed using 3D scanning for a guaranteed perfect fit and proper clearance. The TIG welded construction ensures long-lasting durability, while the high-flow 200-cell catalytic converter with a metal matrix structure provides maximum flow with reduced emissions and odor. The kit is all-inclusive, containing the downpipe, midpipes, and all necessary hardware for installation. For optimal performance, Stage 2 ECU tuning is required, and an IE air intake and IE FDS intercooler are highly recommended. Installation should be performed by a professional, preferably on an auto lift. All-wheel drive (AWD) Quattro or 4 Motion vehicles require a different mid-pipe section (IE Part Number: IEEXCI1). It is not for sale or use in California, USA, or any other jurisdiction where prohibited by law. Integrated Engineering, LLC makes no representations or warranties regarding compliance with applicable emissions laws and expressly disclaims any such claims.
