GM Duramax 6.6L L5P Stainless Up-Pipes (2017-2024)

Upgrade your exhaust system with Stainless Steel Up-Pipes designed specifically for the 2017–2024 GM 6.6L Duramax L5P. These high-performance replacements address a common failure point in the factory exhaust manifold by eliminating the restrictive, leak-prone bellows found in OEM pipes.

Constructed from heavy-duty 304 stainless steel, these up-pipes are engineered to withstand extreme Exhaust Gas Temperatures (EGTs) while improving turbo spool-up and overall airflow efficiency.
