Smeding Diesel 2003-2007 Ram 2500/3500 5.9L Cummins 2 PC OEM/T3 Replacement Exhaust Manifold
Smeding Diesel 2003-2007 Ram 2500/3500 5.9L Cummins 2 PC OEM/T3 Replacement Exhaust Manifold
A 2-piece, T3-flange replacement manifold for the 2003-2007 5.9L Cummins and a direct upgrade over the crack-prone factory unit. The 2-piece design absorbs the thermal expansion that splits stock manifolds, so it survives the heat cycling that kills the original. Cast from high-ductile iron for strength, with pressed hydraulic joints for a guaranteed leak-free connection.
Add the exhaust gasket set and hardware set to install it in a single order.
Built in the USA. 1-year unlimited-mileage warranty.
