2007.5-2018 Cummins 2-Piece OEM Replacement Exhaust Manifold (07182PT4IEM)

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 2-piece semi-divided manifolds are an ideal OEM replacement, offering 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.

• Cast of high-silicon ductile iron to withstand extreme temperatures 
• Thick-walled castings prevent cracking and exhaust leaks
• Fully EGR compatible
• Compatible with the OEM turbo flange
