Wehrli 01-04 Chevrolet 6.6L Duramax LB7 2in Stainless Passenger Side Up Pipe w/Gaskets (Twin Turbo)

Wehrli Custom Fabrication is known for building robust performance parts for diesel trucks. If you're setting up a compound or twin turbo system on your 2001-2004 Chevrolet Silverado 2500 HD or 3500, or your GMC Sierra 2500 HD or 3500 with the 6.6L Duramax LB7 engine, this passenger side up pipe is a key component. It replaces the factory pipe, which can be prone to leaks and cracking, with a much stronger, full-flow design.

This 2-inch diameter up pipe is constructed from 11-gauge stainless steel and is fully TIG welded for durability. The design features less aggressive bends than pipes intended for single turbo applications, which helps increase turbo spool-up speed and can lower Exhaust Gas Temperatures (EGTs). It's important to note that this pipe is specifically for compound/twin turbo setups and will not clear a conventional downpipe routed behind the engine. It is compatible with factory exhaust manifolds or Wehrli's own billet exhaust manifolds.

This kit includes the necessary up pipe gaskets to ensure a solid seal. It's a well-built part designed to handle the demands of a performance diesel engine.
