Injen Technology engineers are true performance gurus. Whether it's cars, trucks, or powersports, Injen offers a wide range of exhaust systems. All Injen performance exhaust systems are made from mandrel - bent stainless - steel tubing. Mandrel - bending keeps the tubing's shape and size consistent for smooth, unrestricted airflow. From investment - cast flanges to custom hangers, these exhaust systems are 100% TIG welded and hand - crafted in the USA. They come with all the tubing, mufflers, and hardware for an 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 - 2013 INFINITI G37 Base, 2011 - 2013 INFINITI G37 IPL, 2008 - 2013 INFINITI G37 Journey, 2008 - 2013 INFINITI G37 Sport, and 2009 - 2013 INFINITI G37 X models.
