WCFab 2001-2004 Chevrolet/GMC 2" Stainless Passenger Side Up Pipe (6.6L) - WCF100654
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2001-2004 Chevrolet Silverado and GMC Sierra 2500 HD / 3500 (6.6L LB7 Duramax).
Replace the leak-prone, 16-gauge factory passenger side up pipe in your LB7 Duramax with this heavy-duty 2-inch stainless steel upgrade from WCFab. Designed specifically for single turbo applications where the turbo is mounted in the factory valley location, this up pipe features a significantly thicker 11-gauge wall construction and an upgraded HD stainless bellow. Unlike the thin OEM bellows that are prone to cracking and exhaust leaks, the WCFab design provides long-term durability and handles the high heat and pressure of performance diesel applications.
The larger 2-inch diameter improves exhaust flow compared to the restrictive stock pipe, helping to decrease Exhaust Gas Temperatures (EGTs) and improve turbo spool-up response. This up pipe is engineered to clear conventional downpipes behind the engine and is fully TIG welded for maximum strength and precision fitment.
- Manufacturer Part Number: WCF100654
- Replaces GM Part Number: 97302261
- Material: 11-Gauge Stainless Steel
- Finish: Raw Stainless
- Bellow Type: Heavy Duty Stainless Bellows
- Design: Fully TIG Welded
- Fitment Note: Compatible with OEM exhaust manifolds or WCFab Billet Exhaust Manifolds (WCF100363) only
- Included: (1) Passenger Side Up Pipe, (2) Up Pipe Gaskets
