2007.5-2018 Cummins 2-Piece T4 Replacement Exhaust Manifold (07182PT4EM)

Fits

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, which is easily identifiable by a ticking sound. Dont bother trying to repair it, upgrade! Smeding specializes in a wide variety of performance parts for the Cummins platform. 

These T4 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.
