Skunk2 is proud to announce the release of our 76mm Megapower RR Exhaust system for the 2012 Honda Civic Si Sedan.

A properly designed exhaust system is critical to engine performance. Skunk2's 76mm MegaPower RR Exhaust system for the 2012 Civic Si sedan was developed with this in mind and is based off of more than 15 years' worth of racing experience. MegaPower RR systems are constructed of T-304 stainless steel, are robotically TIG welded, and feature CNC mandrel bends for a precise fit. Featuring Japanese-spec, Super N1 styling, MegaPower RR Exhaust systems generate more horsepower by optimizing engine airflow and volume through carefully selected, application-specific tubing lengths and diameters and increased wave scavenging effects for more horsepower. CNC mandrel bending allows for a constant tubing diameter throughout the bend, which results in precise fitment as well as improved exhaust gas flow. Each system is fitted with a resonator, includes stainless steel flanges, and is finished off with a straight-through, low-restriction racing muffler for uninterrupted flow. Each fully polished muffler is mated to a 110mm polished tip with its own acid-etched MegaPower badge and serialized nameplate. A Skunk2 removable silencer and all necessary hardware are also included.

The MegaPower RR for the 2012 Civic Si in conjunction with the Skunk2 Alpha Header Downpipe for the 2012 Civic Si has seen hp gains of 30+hp.
