PPE OEM-Length Replacement High-Flow Up-Pipe Kit (2002-2004 CA GM 6.6L Duramax) - (116120204
Overview
The California-emissions 2002-2004 GM 6.6L Duramax engines use factory up-pipes that are prone to corrosion, restrictive bends, and bottlenecks that limit turbocharger efficiency. PPE's OEM-Length Replacement High-Flow Up-Pipe Kit upgrades these weak points with a smoother-flowing stainless steel design that increases exhaust capacity and improves overall engine performance.
High-Flow Stainless Steel Construction
Manufactured from premium stainless steel, these up-pipes eliminate the narrow OEM choke points and tight bends that restrict exhaust flow. PPE's revised design increases the flow area by up to 46%, allowing exhaust gases to move more freely and reducing pumping losses under load.
Durable, Internally Sleeved Bellows
Each up-pipe features a three-layer, internally sleeved bellow for maximum durability and heat resistance. This construction helps maintain structural integrity during extreme temperature cycles, making the kit suitable for both stock and performance applications.
Direct Bolt-On Replacement
Designed as a true OEM-length replacement, these up-pipes bolt directly to the factory exhaust manifolds with no modifications required. PPE includes stainless steel gaskets to ensure a clean, leak-free installation.
Key Features
- Up to 46% larger flow area compared to stock
- High-flow design reduces restriction and improves turbo efficiency
- Premium stainless steel construction for long-term durability
- Three-layer internally sleeved bellows for superior strength
- Includes stainless steel up-pipe gaskets
- Direct bolt-on replacement for OEM up-pipes
- GTIN: 840171209402
- OEM Reference: GM 97246389
Performance Benefits
By eliminating the restrictive OEM bottleneck and improving exhaust flow, PPE's high-flow up-pipes help the turbocharger operate more efficiently. This results in smoother exhaust movement, reduced back-pressure, and improved overall engine responsiveness.
