MegaPower R 70mm Cat-Back Exhaust System

The Skunk2 MegaPower R Cat-Back Exhaust System is engineered to significantly enhance engine performance for the 2006-2011 Honda Civic Si coupe. Developed with over 15 years of racing experience, this system prioritizes maximum horsepower gains by optimizing engine airflow and volume. It is designed to accommodate naturally aspirated engines with higher compression, aggressive camshafts, and racing headers, as well as mild turbocharged applications that require increased exhaust flow beyond standard 60mm systems. Constructed from premium T-304 stainless steel, the exhaust system features robotic TIG welding for superior durability and CNC mandrel bends to maintain a constant tubing diameter throughout each curve. This precise construction ensures not only a perfect fit but also improved exhaust gas flow. The system includes a resonator, stainless steel flanges, and a straight-through, low-restriction racing muffler, all contributing to an optimized exhaust note and performance. Visually, the MegaPower R system boasts Japanese-spec, Super N1 styling, highlighted by a fully polished muffler finished with a 110mm polished tip. The tip is adorned with an acid-etched MegaPower badge and a serialized nameplate, adding a custom aesthetic. For users seeking a quieter operation, a Skunk2 removable silencer is included, along with all necessary hardware for installation. The system is a direct bolt-on to the OEM catalytic converter, though modifications may be required if used with an aftermarket header that deletes the catalytic converter. Fitment is confirmed for 2006-2011 Honda Civic Si coupe models. While the system is designed as a bolt-on, compatibility with other trim levels may require basic welding and fabrication. Due to its large packaging size, shipping rates are calculated based on dimensional weight. The exhaust is backordered, and an ETA will be confirmed within 1-3 days of purchase.
