JMF O2 Housing with Atmosphere Dump for Evo 7/8/9 *Discontinued*

Replace your restrictive OEM cast O2 housing with JMF's newly redesigned free flowing tubular model. Made completely from 304 stainless steel! The flanges are CNC machined from ½” material and are surfaced after welding for a leak free seal.

The exhaust outlet measures in at 2.5” while the wastage dump is mandrel bent from 1.75" tube. The wastegate passage of the flange is 3D contoured to match the shape of the turbine housing for a smooth transition... a first of it's kind! Each unit comes with a machined ring for the OEM donut gasket and a stainless steel divided turbine gasket. Fits all radiators and MOST intercooler pipes.

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

Vehicle Fitment:

REQUIRES CUTTING OF THE PLASTIC UNDER PANEL TO PROPERLY VENT EXHAUST GASES.

Install Tip:
Removing the studs on the turbine housing will allow for a much easier install of the new housing. Slight tweaking of the AC line will be required for proper clearance.
