Injen Technology engineers are true masters of performance. Whether it's cars, trucks, or powersports, Injen offers a wide range of exhaust systems. Their performance exhaust systems are crafted from mandrel - bent stainless steel tubing. Mandrel - bending keeps the tubing's shape and size consistent, allowing for smooth, unrestricted airflow. From investment - cast flanges to custom hangers, all Injen exhaust systems are 100% TIG welded and hand - made in the USA. They come with all the tubing, mufflers, and hardware for easy installation. Each system is uniquely designed to produce an aggressive sound and unleash massive power. Like all Injen products, these exhaust systems are proudly built in Pomona, CA. This part fits 2008 Honda Civic MUGEN Si and 2006 - 2011 Honda Civic Si models.






Using this Injen exhaust system is easy. First, gather all the included tubing, mufflers, and hardware. Then, follow the installation instructions provided to attach the exhaust system to your vehicle. It's designed for a hassle - free installation. When using the exhaust, you'll notice an aggressive sound and enhanced power. As for maintenance, regularly check the connections to make sure they're tight. Keep the exhaust clean by washing it with mild soap and water. Avoid using harsh chemicals that could damage the stainless - steel tubing. If you notice any unusual noises or performance issues, have it checked by a professional.
