GM / LMM Duramax / Exhaust 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.
