3.0T 2.5-Inch Stainless Steel Downpipes

The Integrated Engineering IEEXCG2 downpipe system is designed to unleash the performance potential of the 3.0T Supercharged engine by replacing the factory resonators and muffling components. Installation is straightforward, designed as a direct bolt-on upgrade that can be performed with minimal tools in a home garage. This system replaces approximately 12 feet of factory tubing and the resonators, freeing up the exhaust system to produce a deeper, more assertive exhaust note. Power gains of 8-12 horsepower and torque are expected, with potential for larger gains on more aggressive engine setups.
