ATS Pulse Flow 2 Piece Exhaust Manifold Kit 07.5-18 Ram 6.7L Cummins

That's right, this manifold is a DIRECT replacement for the stock manifold, but with all of the added performance benefits of an ATS Pulse Flow! Nearly all other exhaust manifolds on the market for 6.7L Cummins require you to be running an aftermarket turbo and to have eliminated the factory EGR cooler, but not this one!
The Pulse Flow Exhaust Manifold for 6.7L Cummins features the best in reliability, ease of installation, exhaust temperature stability, and performance. ATS engineered, tested, and manufactured to give you unfailing dependability and performance. The Pulse Flow comes with the factory Holset flange and dual EGR ports to keep your vehicle emissions compliant!

Stock manifolds create cavitation and disrupted air flow, while the ATS Pulse Flow, high-flow design allows exhaust gas a smooth, even and unrestricted flow into the turbocharger.

Fully assembled two piece construction with black, high temperature coating, the 6.7L Pulse Flow Manifold is pre-tapped for the factory EBP (Exhaust Back Pressure) probe, alleviating the need for any drilling or welding! This 2 piece design allows for better thermal expansion and contraction so the chance of cracks and warping is greatly reduced. Multiple pieces also makes installation simple and any future replacements easier.
