GrimmSpeed Header Crosspipe WRX (2008-2014) STI (2004-2018) Volkswagen For the WRX/STI 08-10The Subaru WRX STI LGT is supplied with a small diameter crosspipe from the factory. The problem with this is that 50% of the exhaust gases need to travel through the crosspipe, and that can not be done fast enough with the OEM crosspipe in place. Do not worry though, the GrimmSpeed HiFlow Exhaust Manifold Crosspipe for the OEM header is the solution! The GrimmSpeed HiFlow Crosspipe is made of 304 SS (all of it, the flanges, flex section and tubing)
