ALL MANIFOLDS NOW
COME WITH A BLACK CERAMIC COATING!!!
Our 3-Piece Exhaust Manifold is both a great performance
manifold and a factory replacement
manifold. This 3-Piece Manifold has expansion joints to prevent
cracking and warping so common with the stock manifolds. Built for the
Dodge Cummins, 12-valve engines.
Features Include:
-
Flow tested and balanced for increased balanced exhaust
flow, while maintaining velocity for increased turbo spool up.
-
Includes block gaskets, and two bolts.
-
Drilled/Tapped for pyrometer and pressure fitting.
-
Made from Poly-Bendum Ductile.
-
Comes pressed together, pressure tested and ready to
install.
Below shows the pictures of a stock manifold
on a Cummins, which had shrunk so much from heat that after pulling one
bolt out, the holes in the manifold were over 1/4 inch off from the
head holes. The bolt wouldn't even go back in, and the manifold had to
be cut off. It would have eventually broken either the manifold or
head. It was replaced with our 3-Piece Manifold, and will never have
that problem again. This truly shows the need for this three piece
manifold.
Awesome 3 piece for the price!!!
