Designed as an OEM replacment Mid-Pipe that can be used in conjunction with the OEM Axle-Back section or any aftermarket Axle-Back system. The EP3 Civic has several tight bends and a heavy and restrictive Resonator; the Megan Racing mid-pipe is constructed of durable T-304 Stainless Steel that is lighter than the OEM piping and has smoother mandrel bends.The Perforated Core resonator is perfect for reducing noise and interior resonance without sacrificing performance while the larger 2.25″ piping increases performance through-out the Mid-to-Upper end of the powerband.NOTE: Only a donut gasket, as pictured, is included. Spring bolts and rubber hangers (OEM) are to be re-used.NOTE: All Megan Racing Exhaust and Suspension products are deemed for “off-road use only”– please check local laws regarding the modification of the exhaust systems by checking the vehicle code for your state. Many states are more stringent on exhaust modification laws and to pass SMOG. Please check your local laws.
