2019-2022 Cummins 2-Piece OEM Replacement Exhaust Manifold

Fits: 

Note: Will not fit Cab & Chassis models (Modifications are required)

We think it's safe to say that factory exhaust manifolds on any of the big three diesels are just atrocious. They crack easily, warp, and make horrendous noise. Dont bother trying to repair it, upgrade! Smeding specializes in a wide variety of performance parts for the Cummins platform. 

These 2-piece manifolds offer better thermal expansion and contraction to eliminate the possibility of cracking or warping, effectively providing you with improved exhaust flow, reduced back pressure, quicker turbo spooling, increased horsepower, and fuel economy.
