JM FABRICATIONS O2 HOUSING EXTERNAL DUMP (EVO 7/8/9)
Replace your restrictive OEM cast O2 housing with our newly redesigned free flowing tubular model. Made completely from 304 stainless steel! The flanges are CNC machined from ??" 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 intercooler pipes.
***FOR OFF-ROAD USE ONLY, 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.
