One of the first modifications that should be done to any serious tuner car is a high quality exhaust system. The Injen Technology SES performance catback serves as a triple threat by adding performance, head-turning looks and a unique throaty exhaust tone to your BRZ. All Injen SES exhaust systems are mandrel bent and robotic TIG welded from high quality 304 stainless steel. Flanges are CNC cut to exacting vehicle specific tolerances, eliminating the chance of warpage and ensuring leak free performance that will last the life of your car. Injen SES exhaust systems for the FR-S feature full stainless steel piping and Injen's unique flared burnt titanium tips, a feature not available from any competing system. Unwrap an Injen SES exhaust and there will be no question that you have made the right choice.
