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

When you're looking to get the most out of your 2006-2011 Honda Civic Si coupe, the exhaust system plays a big role. This Skunk2 MegaPower R 70mm cat-back exhaust system is built to help your engine breathe easier and make more power. It's designed to replace your stock exhaust from the catalytic converter back, and it includes the main exhaust tubing, a resonator, a straight-through racing muffler, a polished 4-inch tip with an acid-etched badge, a removable silencer, and all the necessary hardware to get it installed. Skunk2 has over 15 years of racing experience behind this system, and it's proven on the dyno to help increase horsepower.

This MegaPower R system is constructed from T-304 stainless steel, which is known for its strength and resistance to corrosion. The tubing features CNC mandrel bends, meaning the diameter stays constant through the bends, ensuring a precise fit and smooth exhaust flow. The larger 70mm (2.75 inch) diameter piping is ideal for naturally aspirated engines with modifications like higher compression, aggressive camshafts, or racing headers, as well as for mild turbocharged setups that need more exhaust flow than a smaller 60mm system can provide. This larger diameter and the straight-through muffler design contribute to a significantly louder and more aggressive exhaust tone compared to smaller systems, giving your Civic Si a distinct Japanese-spec Super N1 styling.

Because this is a bolt-on system, no welding or fabrication is required for installation, making it a straightforward upgrade. The system also includes a removable silencer, giving you the option to reduce the exhaust volume when needed. This exhaust is built for maximum flow and power, allowing your engine to perform at its best.
