Skunk2 MegaPower R 06-08 Honda Civic Si (Sedan) 70mm Exhaust System

Skunk2 Racing has over 15 years of racing experience, and they've put that knowledge into their MegaPower exhaust systems. For your 2007-2011 Honda Civic Si sedan, this 70mm MegaPower R cat-back system is built to help your engine breathe easier, especially if you've made other performance upgrades like higher compression, aggressive cams, or even a mild turbo. It's designed to let your engine perform at its best.

This system is constructed from T-304 stainless steel, which is known for holding up well over time. The tubing features CNC mandrel bends, meaning the diameter stays consistent throughout the bends, which helps exhaust gases flow smoothly. This larger 70mm piping allows for more flow and power compared to smaller 60mm systems, and it's paired with a resonator and a straight-through racing muffler for maximum flow. You'll notice a significantly louder and more aggressive tone with this system, especially compared to the 60mm versions. It's finished off with a polished 110mm tip that has an acid-etched MegaPower badge and a serialized nameplate, giving it a distinct look.

This is a bolt-on system, so no welding or fabrication is needed for installation. It comes with everything you need, including a removable silencer if you want to quiet things down a bit, and all the necessary hardware. This system is based on the same designs Skunk2 uses for their own road racing and time attack vehicles.
