A properly designed exhaust system is critical to engine performance. Skunk2's 60mm MegaPower Exhaust system for 96 - 00 CX and DX hatchbacks featuring B - series engine swaps 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 cat - back 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 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.
