A properly designed exhaust system is critical to engine performance. Skunk2’s 76mm MegaPower RR Exhaust system for the 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 Civic Si in conjunction with the Skunk2 Alpha Header for the 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. MegaPower Exhaust systems offer more performance, better build-quality, and the ultimate sound when compared to comparably priced systems.

My order shipped within two days. Couldn’t ask for a better sounding exhaust has a nice deep tone, definitely worth the money!
I think this exhaust is more hype then performance With a skunk 2 cold air intake (not short ram ) the full cold air intake and this exhaust I really don’t feel any difference at all from stock unless you get a hi flow catalytic converters or run a straight pipe don’t even bother just buying these Two items you need a header intake manifold and a drop down to a straight pipe otherwise you have to supercharger or a turbo charger to really get some real change in power but then you have to replace a lot of parts which gets crazy expensive like upwards of ten to twenty thousand dollars not to many people wanna do that when they can buy a type r civic idk this is all my opinion but the exhaust does have a deep nice loud tone not like a weed hacker or lawn mower like other cheap river exhausts on 96 civic lx with shitty spray painted hubcaps and crappy details you might also need a tune up if you replace your si with a skunk 2 intake and exhaust maybe get a vetch controller to get the air and fuel ratio straightened out just my opinion just putting it out there but it is a beautiful exhaust
