Dieselr Driver Side Up-Pipe Duramax LB7/LLY/LBZ/LMM/LML 6.6L (2001-2016)

Driver Side Up-Pipe for 6.6L Duramax

The Dieselr Driver Side Up-Pipe Duramax LB7/LLY/LBZ/LMM/LML 6.6L (2001-2016) is a direct-fit replacement engineered for proper exhaust routing from the driver side exhaust manifold to the turbocharger. Built specifically for 6.6L Duramax applications, this component restores structural integrity and sealing reliability in the high-heat up-pipe section.

Designed around factory turbo location and manifold geometry, it maintains correct alignment across LB7, LLY, LBZ, LMM, and LML platforms.
