Skunk2 Mega Power RR Exhaust - FG4/FB6 Cvic Si
The Skunk2 MegaPower RR is one of those Honda Civic Si performance exhausts that actually moves the needle. On a 2012–2015 Civic Si, this high-flow Civic Si exhaust uses full 76mm (3") T-304 stainless from front to back, so you’re not choking the car once you add header, intake, or boost. It’s aimed at 9th gen cars that aren’t stock forever—built NA or turbo—where you actually need a racing exhaust Civic Si system that doesn’t become the bottleneck. Skunk2 uses CNC mandrel-bent tubing for consistent diameter through every bend, robotically TIG-welded joints, and proper hanger placement so it fits like it should. Both the Skunk2 76mm exhaust Civic coupe (SKU: SK2-413-05-6050) and sedan (SKU: SK2-413-05-6055) versions give you real Civic Si exhaust horsepower gains by cutting backpressure instead of just making more noise. We still run this exact stainless Skunk2 exhaust Civic setup on our own 9th gens.
The MegaPower RR leans hard into that Japanese style Civic exhaust vibe—think Super N1 look, but sized for real power. Oversized 76mm piping and a straight-through racing muffler mean flow comes first, sound second. You get a deep, aggressive tone that actually sounds like a fast car, not a tin can, and it comes with a resonator to keep the worst rasp in check. At the back there’s a polished 110mm tip with the Skunk2 MegaPower badge, so any Honda nerd knows what they’re looking at. This Skunk2 9th gen Civic exhaust includes a removable silencer if you need to keep things a little calmer, plus all the hardware you need to bolt the Skunk2 exhaust 12–15 Civic Si system up without a bunch of extra parts-hunting. It’s a Skunk2 CNC bent exhaust with robotically TIG-welded seams, built for people who actually care about flow numbers and track days, not just parking-lot revs.
