Located after the midpipes and before the catback, IE's X-pipe replaces the middle section of factory tubing and the sizeable suitcase center resonator. Upgrading this section removes the massive resonator and ultimately frees up the middle of the exhaust system improving flow and exhaust sound.


IE's X-pipe replaces the factory suitcase muffler with straight pipes that retain the center cross-section exhaust path. This design maintains the proper balance of exhaust pulses, increases exhaust gas flow, and produces a tuned exhaust sound without annoying cabin drones or rasp.


The X-pipe is manufactured from CNC mandrel bent and TIG-welded high-quality 304 stainless steel tubing. This material is the high-end choice for exhaust systems for its lighter weight and superior corrosion resistance. OE-quality clamps are included to ensure no annoying leaks or performance issues. Enjoy a perfect fit and long-life enjoyment of your exhaust system upgrade.


IE engineers employ leading-edge 3D scanning and rapid prototyping technology to ensure our X-pipe provides a perfected alignment with both factory and IE upgrade parts without any interference, rubbing, rattles, or fitment issues.
