FOR THOSE WHO DEMAND THE BEST ALWAYS GO WITH GRIMMSPEED

The GrimmSpeed Limited Catted Downpipe is the result of countless hours invested in research and development to provide the performance consumer with a quality product guaranteed to deliver performance. This is a direct replacement of the OEM downpipe that is highly restrictive and leaves much room on the table for improvement. The GrimmSpeed unit combines smooth bends and a larger piping diameter to remove as much turbulence from the exit path of the turbocharger which will add more horsepower, and more torque while reducing the turbo lag.
