ATS Pulse Flow Exhaust Manifold

The 6.7 Cummins ATS Pulse Flow Exhaust Manifold upgrade increases reliability, performance and improves exhaust flow while eliminating the common cracking issues with your stock exhaust manifold. Designed as a drop-in upgrade, this exhaust manifold bolts in place of your factory manifold and has front and rear EGR ports to retain your factory EGR System. The Pulse Flow 2-Piece manifold also features a patented ball flange design that allows for expansion and contraction without cracking like the factory exhaust manifold.
