Skunk2 MegaPower RR 76mm cat-back exhaust for the 2012 Honda Civic Si (4-door) is a bolt-on T-304 stainless steel system engineered for maximum flow and power. Robotically TIG-welded with CNC mandrel bends, it includes a resonator, stainless flanges, hardware, and a straight-through racing muffler mated to a 110mm polished tip. Intended for heavily modified NA or turbo setups, it delivers larger-diameter flow and a louder, race-inspired tone.
