Full 76mm Mandrel-Bent Piping:

The Skunk2 MegaPower RR features full 76mm (3-inch) mandrel-bent piping throughout the entire system. Mandrel bending maintains consistent internal diameter throughout each bend, eliminating the crimping and restriction that occurs with crush bending. This ensures smooth, unrestricted exhaust flow for maximum power gains and improved throttle response.

T-304 Stainless Steel Construction:

Skunk2 uses premium T-304 stainless steel for exceptional durability and corrosion resistance. T-304 grade stainless steel is superior to the more common 304 stainless, offering better resistance to heat and corrosion. This ensures the exhaust maintains its appearance and performance even after years of use in all weather conditions.

Race-Proven MegaPower RR Design:

The MegaPower RR is Skunk2's race-proven exhaust design, tested extensively on track and dyno. The RR (Race Ready) designation indicates this exhaust is engineered for maximum performance, with aggressive sound and proven power gains. This is the same exhaust technology used by Skunk2-sponsored race teams.

Proven Power Gains:

Dyno testing shows the Skunk2 MegaPower RR delivers +12 HP and +10 lb-ft torque on a stock Civic Si Coupe. These gains come from the improved exhaust flow and reduced backpressure compared to the factory exhaust. When combined with other modifications (intake, header, tune), the gains are even more significant as the exhaust supports higher power levels.

Aggressive Race-Inspired Sound:

The MegaPower RR delivers an aggressive, race-inspired exhaust tone that showcases the K20Z3 engine's high-revving character. The sound is loud and exciting during acceleration, especially in VTEC. At cruising speeds, the exhaust maintains a refined tone with minimal drone, making it suitable for daily driving.
