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 is completely freeflowing and the diameter is increased with 27% to 3″/76mm. 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! Also available with sports CAT.
