JM Fab Stock Replacement 7CM Exhaust Manifold - DSM

Product Details

Part # DSM-EXMANI-15

Replace your restrictive OEM cast exhaust manifold with our high flowing tubular model.� By far the best DSM stock replacement manifold on the market today!� With 100's of these manifolds sold around the world, you won't find a nicer piece!�

Made from thick walled 304 stainless steel tubing, this manifold is an exact replacement for the stock unit and no other modifications are required. Features near equal length runners with multi-pass TIG welded joints. All flanges are CNC machined from 304 stainless steel and surfaced to ensure a leak free seal.� The ports are gasket matched and smoothed to perfection for the best of flow!

Install Tips:

Studs instead of bolts will need to be used on the front 2 bolt holes of the turbine flange.

The nut above runner #3 must be installed while the manifold is hanging off the head studs prior to placing it against the head.

It is HIGHLY recommended to use a 4-layer MLS gasket, if not the stud above the #3 runner will need to be trimmed slightly.

Aftermarket head studs that are longer than OEM may have clearance issues.

Due to the tight tolerances required for this manifold those using it on a 2G head may need to slightly grind down a small portion of casting on the face of the head.
