Skunk2 Mega Power R Exhaust – Civic Si '02–'05 | 413-05-5020

The Skunk2 Mega Power R Exhaust System is engineered for serious performance gains in the 2002–2005 Honda Civic Si. Designed with experience gained through motorsport development, this system features larger diameter tubing than the standard MegaPower line, delivering enhanced exhaust flow and proven horsepower gains on the dyno.

Constructed entirely from high-grade T-304 stainless steel, the Mega Power R system uses precision mandrel bends and is robotically TIG welded to ensure strength, durability, and a refined finish. A low-restriction Super N1-style muffler with a 110mm polished tip and Skunk2 badge provides aggressive aesthetics and sound. The system is a complete bolt-on solution, requiring no welding or fabrication, and includes a removable silencer and installation hardware.
