2017-2021 GMC Sierra 2500HD/3500HD 6.6L L5P Duramax Diesel 3.5" High Flow Exhaust Up Pipes

Feature:
Upgrade the L5P to achieve higher-flow by bolting on PPE OEM-Length Replacement High-Flow Up-Pipes.
These direct replacements have a 46% larger flow area over stock, which results in a deeper-breathing power-plant, while maintaining the mandated Federal emissions standards of stock.
The Length Up-Pipes are manufactured from stainless steel. These new Up-Pipes include the superior internally-sleeved bellows, also manufactured from stainless steel.
This system is engineered to take the abuse of high temperatures and high pressures, while promoting increased exhaust flow and lower EGTs.
