PPE Replacement Up-Pipe for OEM Exhaust Manifold - Driver Side (2017-2026 GM 6.6L Duramax) - (116122005
Overview
PPE's Driver-Side Replacement Up-Pipe is engineered as a direct bolt-on upgrade for 2017-2026 GM 6.6L Duramax engines. Designed to replace the restrictive factory up-pipe, this unit improves exhaust flow, reduces back-pressure, and helps restore turbocharger efficiency on L5P-equipped trucks.
High-Flow Stainless Steel Construction
Built from 11-gauge 304 stainless steel with a .120-inch wall thickness and a 2-inch outer diameter, this up-pipe delivers exceptional durability and smoother exhaust flow. The internally sleeved stainless steel bellow is designed to withstand extreme heat and pressure while maintaining long-term flexibility.
Improved Turbo Response & Lower EGTs
PPE OEM Up-Pipes offer up to 53% more exhaust flow than the stock design. This increase helps the turbo spool faster, reduces pumping losses, and lowers exhaust gas temperatures for improved overall performance and reliability.
Direct Bolt-On Replacement
This up-pipe installs directly onto the factory exhaust manifolds with no modifications required. It also serves as the replacement driver-side up-pipe used in PPE's High-Flow Up-Pipe Kit (SKU 116122000).
