K-TUNED EP3 Cat Back Exhaust System. Developed to offer maximum overall performance and excellent fitment, something that until now has been quite difficult to accomplish on the EP3 chassis. We already know that 3" piping reduces restriction and offers the K series engine significant power gains, especially in the higher rpm range. The problem with larger diameter EP3 exhaust systems has been fitment because standard 3" round piping under the EP3 chassis hangs way too close to the ground. The key feature of the K-TUNED EP3 Exhaust System is the uniquely designed oval tubing mid pipe, which solves the ground clearance problem and maximises exhaust flow. There shouldn't be anymore scraping on driveways or speed bumps because the 3" nominal size oval mid pipe actually hangs at the exact same height as the factory exhaust. The over axle section includes a resonator and fully polished stainless steel muffler with double wall slash cut tip. All hardware and gaskets are included. Last, for anyone who has questions about sound keep in mind that this is an aggressive, race inspired, straight through exhaust system so it will make some noise. The system is a direct bolt on for all 01 05 EP3 Civic.
