Non-toxic Wehrli 01-04 Chevrolet 6.6l Duramax Lb7 2in Stainless Passenger Side Up Pipe W/gaskets (twin Turbo) Pro Version [kweH7pAd]

Heavy-Duty 2" Stainless Steel Up Pipe

Upgrade your 2001-2004 Chevrolet or GMC 6.6L Duramax LB7 with this top-of-the-line stainless steel up pipe. This robust replacement for the OEM passenger side up pipe is designed to enhance performance and durability. Crafted from 11-gauge stainless steel, this up pipe boasts a heavy-duty construction that stands up to the rigors of high-performance applications.
  • Stainless Steel Construction: 11-gauge stainless steel for unmatched durability and resistance to corrosion.
  • HD Bellows: Heavy-duty stainless bellows that won't crack or leak like the OEM part, ensuring a longer lifespan and improved performance.

Optimized Design for Twin Turbo Applications

This up pipe is specifically designed for use in compound or twin turbo style applications, offering a more sweeping, less aggressive bend to maximize airflow and efficiency. It's built to complement twin turbo setups, helping to increase turbo spool-up and reduce exhaust gas temperatures (EGTs). Note that this up pipe is compatible only with factory exhaust manifolds or WCFab Duramax Billet Exhaust Manifolds (WCF100363) and will not clear a conventional downpipe.
  • Engineered for Performance: Sweeping design for optimal airflow and increased turbo spool-up.
  • Reduced EGTs: Less aggressive bends to reduce exhaust gas temperatures for better overall engine performance.

Perfect Fitment and Compatibility

This high-quality up pipe is a perfect fit for a wide range of vehicles, including the Chevrolet Silverado 2500/3500 and GMC Sierra 2500/3500 models from 2001 to 2004. With its precise engineering and fitment, it ensures a seamless installation process and maintains the integrity of your exhaust system.
  • Wide Range of Applications: Fits 2001-2004 Chevrolet and GMC models with a 6.6L Duramax LB7 engine.
  • Seamless Installation: Designed for easy installation with all necessary gaskets included.
Experience the difference with this heavy-duty up pipe – the perfect choice for those seeking improved performance and longevity for their Duramax-equipped trucks.
