Stainless steel 3″ exhaust system to replace the stock catalyst and front pipe. The factory cat is placed directly at the turbine, creating a lot of backpressure. With this turbo back system the exhaust diameter is increased with 27% to 3″/76mm and with the option to add a highflow 200 cpsi cat which is mounted more downstream. The result is a drastic reduction of backpressure, which creates better turbo response, more power and lower exhaust gas temperature (EGT). This system is a must have for 300+ hp projects.
