Invidia Racing Series Cat Back Exhaust - 2008-2014 WRX Hatch
This is the Invidia Racing Series Cat-Back Exhaust System. This exhaust system features a design that combines minimal bends with a larger piping diameter. This will allow for an unobstructed exit of exhaust gases with minimal restrictions and turbulence. This will allow for improvements in both horsepower and torque, along with improvements in throttle response with a reduction in turbo lag. Additionally, you get the reward of an aggressive exhaust note.
