BETTER EXHAUST FLOW FOR BETTER PERFORMANCE

This is the GrimmSpeed HiFlow Exhaust Manifold Crosspipe. This is generally an overlooked exhaust component, however, GimmSpeed has taken into consideration that this particular component will experience 50% of the exhaust gases passing through this tiny pipe which leaves a lot of room for improvement. GrimmSpeed has invested its time, knowledge, and fabricating craftsmanship to provide you with a high-performance solution aimed to improve your overall performance. Note that this particular cross pipe will come ceramic coated in a black finish to help reduce the overall exhaust temperatures.
