The Injen Technology engineers are experts when it comes to performance, PERIOD. From Cars to Trucks to Powersports, Injen has a variety of exhaust systems to choose from. All of Injen Technology Performance exhaust systems are constructed from mandrel bent stainless steel tubing Mandrel-bending ensures the tubing maintains its shapes and size throughout the entire length, providing smooth, unrestricted airflow. From the Investment cast flanges to the custom hangers, all Injen exhaust systems are 100% TIG welded and handcrafted in the USA and include all tubing, mufflers, and hardware necessary for a hassle free installation. Each system is uniquely designed to offer an aggressive sound that brings out some massive power. Like all other Injen products, the Injen exhaust systems are proudly built in Pomona, CA.

Designed for specific vehicles the Injen Titanium Tip (TT) Edition gives the Super SES exhaust line its added flare. With a more aggressive burnt titanium tip finish larger diameters (where applicable) and featuring a slip fit design- the Injen SES TT edition has proven to be the next best thing since the release of the SES line.
