JMF Stock Replacement 7CM Exhaust Manifold for 1G/2G DSM * Discontinued*
Discontinued - No Longer Available
This manifold is no longer in production.
The JMF Stock Replacement 7CM Exhaust Manifold for 1G/2G DSM is an exact replacement for the stock unit with no other modifications required. Available with or without a external wastegate flange. Made from thick-walled 304 stainless steel tubing and 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. Available with or without a external wastegate flange.
Vehicle Fitment:
1990-1999 Eclipse GST/GSX
1990-1998 Talon TSi
1990-1994 Laser RS
Includes:
(1) Manifold
Install Tips:
Instead of bolts, studs will need to be used on the front two 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.
