3" Down Pipe, Chevy/GMC 6.6L Duramax 2004.5 - 2010

Replace that restrictive factory downpipe with a MBRP direct replacement downpipe for more flow, fuel economy, and better performance.

While the search for more power for your LLY, LBZ or LMM Duramax powered vehicle usually leads you down the path of exhaust, intake and tuner, one item that is often overlooked is the factory restrictive turbo direct pipe. MBRP has addressed this restrictive component of the factory exhaust with our new turbo direct pipe replacement that mounts between your factory turbo and your exhaust system. Featuring full 16 gauge mandrel bent tubing for maximum flow, and an extremely durable high temperature ceramic coating, these pipes deepen the sound of your V8 diesel engine while lowering EGT's and providing quicker throttle response.

Fits Mid to Late 2004-10 Models. LLY,LBZ,LMM Duramax engines.
