ATS Pulseflow Exhaust Manifolds flow better than OEM units and eliminate cracking and flexing issues. Constant heat cycles, age and performance parts can stress a stock manifold, leading to exhaust leaks, lower boost pressure and poor performance. ATS exhaust manifolds for 1994-2012 Dodge trucks can handle higher temperatures, more heat cycles and help the turbo spool faster. They are all conveniently tapped for an EGT probe – so no drilling or tapping is required.
