DIESELR Up-Pipe - Passenger Side (2001-2016 GM 2500/3500 6.6L Duramax LB7/LLY/LBZ/LMM/LML)

DIESELR Passenger Side Up-Pipe for Duramax 6.6L (2001–2016)

Built from high-grade 304 stainless steel, the DIESELR Passenger Side Up-Pipe for Duramax 2500/3500 trucks is designed to handle serious heat and pressure. The reinforced bellows and precision-fit flanges reduce the risk of leaks and cracks found in stock components.

This passenger side exhaust pipe is a direct-fit solution for 2001–2016 GM Duramax engines (LB7, LLY, LBZ, LMM, LML). It includes the turbo-side and manifold-side gaskets for a tight seal during installation—no guesswork or extra trips to the parts store.

Expect lower exhaust gas temperatures, faster turbo spool, and improved flow without the common failure points of thin-walled factory units. Whether you're daily driving or hauling under load, this replacement pipe is a no-compromise fix built to outlast and outperform.
