17-26 GM 6.6L L5P Duramax PPE Replacement High-Flow Up-Pipes

Fits: 2017-2026 GM 6.6L L5P Duramax 

The PPE 116122000 is a high-flow replacement up-pipe kit for GM 6.6L Duramax diesel engines, designed to replace restrictive or failure-prone factory up-pipes with a stronger, higher-flow stainless steel design

Up-pipes connect the exhaust manifolds to the turbocharger making them critical for exhaust flow and turbo performance.

• Increases exhaust flow to the turbo
• Reduces backpressure in the exhaust system
• Improves:
  • Turbo spool-up
  • Engine efficiency
  • Exhaust gas temperature (EGT) control

PPE up-pipes are known to provide -50%+ greater flow than stock designs depending on application.

• 11-gauge 304 stainless steel construction (much stronger than OEM)
• Internally sleeved bellows:
  • Handles extreme heat & pressure
  • Prevents common cracking failures
• Increased inner diameter for better airflow
• Direct bolt-on replacement to factory manifolds
• Designed for high-performance and heavy-duty use
