GrimmSpeed Cat-Back Exhaust System
The GrimmSpeed Cat-Back Exhaust System is pure stainless steel art that combines a larger piping diameter along with smooth bends to create more horsepower, more torque, all while reducing the turbo lag. This design allows for an unobstructed exit path for the exhaust gases to escape while generating a more aggressive signature Subaru exhaust note.
This exhaust system features quad polished tips and has a built-in resonator in the piping for those of you who want a more respectful noise level, and it can be employed on a full-blown race car, rally car, or daily-driven street car. Note that this particular exhaust has been made to fit the WRX/STI Sedan models only.
