The factory turbo direct pipe on the LML Duramax's is very restrictive. Unfortunately, due to the construction of the factory downpipe, none of the exhaust manufacturers include this piece with their full exhaust kits. MBRP announces the release of their turbo direct pipe that will bolt directly in place of the factory unit and give you a freer flowing exhaust while being completely 50 state emissions compliant. This piece comes powdercoated in black and is built from 16 gauge mandrel bent tubing for maximum flow.
