ATS Pulseflow Exhaust Manifolds flow better more than stock 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. Unlike the factory GM manifolds, ATS does not choke the driver?s side manifold. This allows the maximum flow possible from both the passenger and driver?s side manifolds.

ATS exhaust manifolds for 2001+ GM Duramax 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.

ATS Pulseflow Exhaust Manifolds are backed by a 5 year / 500,000 mile warranty.
