Wehrli 07.5-10 Chevrolet 6.6L Duramax LMM Stage 3 High Flow Bundle Kit - Chevy Orange

The Stage 3 upgrade combines a Stage 2 High Flow Bundle and a 3" Stainless Steel Down Pipe, increasing air and exhaust flow for improved efficiency, throttle response, and turbo spool up. It eliminates weak points in the factory design. The kit includes a high flow fabricated intake pipe, intake horn, and air box enclosure with a dry filter assembly, replacing restrictive plastic factory parts. It features 14 ga. aluminum construction, 4-inch piping, and smooth aerodynamic bends. The 4.8-inch turbo intake horn offers a 20% airflow improvement over stock. The kit also upgrades the 2.5-inch driver (hot) side intercooler pipe and plastic/rubber passenger (cold) side pipe with heavy-duty 3-inch diameter 1-piece Driver (Hot) Side and 3.5-inch diameter Passenger (Cold) Side LMM Intercooler Pipes, made from high strength, heavy-duty 14 ga. aluminum tube. It also includes WCFab's signature high flow 3" Y-Bridge Kit, which replaces the OEM upper intake manifold. The product comes in custom powder coat colors and is compatible with stock trucks, requiring no tuning. It cannot ship to the state of California.
