Grimmspeed HiFlow Exhaust Manifold Crosspipe for 02-05 WRX Sti/LGT
Subaru supplies its turbo owners with a tiny little crosspipe from the factory. 50% of your exhaust gasses are passing through this tiny pipe and, well, that's just a problem. Crosspipes run in very harsh conditions when bolted to your car so it is important to use high quality components otherwise you risk fatigue. Do not worry though, GrimmSpeed has a solution for you!
