K-Tuned EP3 Cat-Back Exhaust Systems have been 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 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 maximizes 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 system is a direct bolt-on for all 02-05 EP3 Civic Hatchback models that are using or switching to an RSX Type-S header. The EP3 muffler needed to be smaller than the RSX design, and it enters at an offset to ensure it will clear the rear swaybar. Note that the entry to the mid pipe has an extremely short section of 2.5" pipe that quickly steps back up to 3". This is necessary because we wanted our system to bolt up perfectly to a stock RSX Type-S header as well as any aftermarket headers that maintain the RSX-S factory connection point. If you have a turbo setup or an aggressive all motor setup you can easily cut this transition off and join it to your down-pipe or header. 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.
Applications: Fits all 02-05 EP3 Civic Hatchbacks that are using or switching to an RSX Type-S header.
IMPORTANT: This exhaust system does not bolt up to the factory EP3 header. An RSX Header must be used.
