Dodge Ram Twin Turbo Kit - Wehrli - S400/Stock - Chevy Orange - 03–07. Designed for 2003–2007 5.9L Cummins trucks, this compound kit pairs an S400 with your stock Holset for responsive, controllable power suited to street, work, or tow builds.

Match the kit to your goals: S475/stock for quick spool and about 750 RWHP with supporting mods; S480/stock for stronger top-end; S480 with 63–64 drop-in for 900+ potential; or S480 with 67 drop-in for the highest top end (not recommended for tow rigs). When configured appropriately, it offers stock-like spool with improved EGT control. Turbochargers are sold separately. Finished in Chevy Orange with high-temp black on the hot side. Uses the OEM exhaust manifold; aftermarket replacement-style manifolds must be sent to WCFab for custom fitment before lead time begins.
