JMF Top Mount Exhaust Manifold for 1G/2G DSM *Discontinued*

The JMF DSM top mounted turbo exhaust manifold is made from thick-walled 304 stainless steel tubing featuring multi-pass TIG welded joints and CNC machined 1/2" thick 304 stainless steel flanges. The ports are gasket-matched and smoothed to perfection for the best flow and each flange is surfaced for a leak free seal. The open T3 and divided T4 versions feature a one of a kind cast merge collector for superior flow and durability. If you choose the divided T4 flange option you will need to run 2 external wastegates.

With this manifold on a 1G you will still be able to keep your power steering and a full size radiator however your fans will need to be relocated. Alternator relocation is required when running a 3.5" or larger exhaust. This manifold is designed to work with a 6-bolt block, it will fit a 7-bolt block but there is a small unnecessary portion of casting on the front of the 7-bolt block that will need to be sanded down slightly. 2G fitment is VERY tight with a full size radiator, it is recommended to use a half sized radiator for an easier install.

Discontinued:
JMF is no longer manufacturing manifolds, downpipes or o2 housings. We currently have none remaining in stock.
