Description

A properly designed exhaust system is critical to engine performance. Skunk2's 76mm MegaPower RR Exhaust system for the 2012 Civic Si coupe was developed with this in mind and is based off of more than 15 years' worth of racing experience. Dyno-proven for maximum horsepower, MegaPower RR systems are constructed of T-304 stainless steel, are robotically TIG welded, and feature CNC mandrel bends for a precise fit. The MegaPower RR for the 2012 Civic Si in conjunction with the Skunk2 Alpha Header for the 2012 Civic Si has seen hp gains above 30hp. Designed for heavily modified naturally aspirated engines as well as for turbocharged applications that require more exhaust flow than Skunk2's 70mm MegaPower R Exhausts provide, MegaPower RR Exhausts allow engines to breathe more efficiently and produce more power thanks to larger diameter piping. MegaPower RR Exhaust systems were designed for maximum flow and power, featuring oversized tubing and mufflers, which result in a significantly louder tone when compared to other MegaPower systems. 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. Skunk2's MegaPower Exhaust systems are based off of the same systems we custom build for our road racing and time attack vehicles.
