Grimmspeed Up Pipe for WRX/STI/LGT/FXT with Black Ceramic Coat

GrimmSpeed Up Pipe for WRX/STI/LGT/FXT with Black Ceramic Coat

Adding an aftermarket Up Pipe is one of the first things you should do to your Subaru. Arguably one of the best $/HP ratios. Our goal was to make a premium heavy duty Up Pipe for you. Up Pipes run in very harsh conditions when bolted to your car so it is important to use high quality components otherwise you risk fatigue.
