Diamond Eye has addressed this restrictive component of the factory exhaust with our new turbo direct pipe replacement that mounts between your factory turbo and exhaust system. Featuring full 16 gauge mandrel bent tubing for maximum flow, and an extremely durable high temp ceramic coating, this pipe deepens the sound of your Duramax while lowering EGT's and providing quicker throttle response.
