Chevrolet Silverado 3500 Turbo Swap Kit - Wehrli - S400 - Cat Yellow - 01-04. For 6.6L LB7, this install kit converts the stock IHI to an S400-based setup.
Wehrli's kit upgrades the air path: 5" aluminum intake with air box and dry filter, 3" mandrel-bent hot/cold pipes, and a 3" billet Y-bridge. A T4 pedestal sets your S400 (turbo sold separately), and the ceramic-coated 3" downpipe mates to the factory front pipe—no cutting. Includes stainless braided oil lines, boots/clamps. S400 Half Marmon 4.6" outlet only; forward-facing thermostat housing WCF100405 required.
