Dorman knows exhaust manifold replacement
is a higher stakes repair today than it used to be.
Limited access, dissimilar head/manifold material
metallurgy and downstream add-ons like manifold
converters and turbochargers make the labor and
cost of this job higher than ever.
Look to Dorman for innovative design and material
upgrades that provide better-than-stock longevity,
like our stainless manifold mounting hardware kits,
specialized ceramic coatings on select applications,
and reinforced casting ribs on manifolds we know
are prone to breaking.

PROBLEM:
Thermal cycling on General Motors vehicles pow-
ered by LS engines can cause some manifolds
to warp and others to crack. Milling and welding
damaged manifolds aren't reliable repair options
given the high labor times involved on many of
these cars and trucks.
FIX:
Dorman's OE FIX driver's side exhaust manifold
is made of nodular cast iron, a better class
of iron than the OE alloy. Dorman manifolds
manufactured from this upgraded material have
superior fatigue resistance to help ensure longer
life and leak-free exhausts.
