PPE OEM-Length Replacement High-Flow Up-Pipes for L5P Duramax
GM trucks equipped with the L5P diesel represent a modern balance of power, efficiency, and design. While they deliver strong performance with low emissions, the factory up-pipes are restrictive and undersized.
PPE’s OEM-length high-flow up-pipes solve this limitation by increasing exhaust flow, improving engine breathing, and maintaining full compliance with Federal emissions standards.
Key Features
- 46% larger flow area compared to stock up-pipes
- Constructed from durable 11-gauge “304" stainless steel
- Internally-sleeved bellows made from “304" stainless steel for added strength
- Direct bolt-on replacement using OEM-length design
- “304” stainless steel gaskets
Benefits
Upgrading to PPE high-flow up-pipes allows your L5P engine to breathe more efficiently, resulting in improved exhaust flow and reduced exhaust gas temperatures (EGTs).
Built to withstand extreme heat and pressure, this system enhances durability while supporting better overall engine performance—making it an ideal upgrade for a modern diesel powerhouse.
