JMFab EVO O2 Housing - Hood Dump

Regular price $465.75 $395.89 Sale

Replace your restrictive OEM cast O2 housing with our newly designed 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 most radiators and intercooler pipes.

***FOR OFF-ROAD USE ONLY, REQUIRES CUTTING OF THE MESH INSERT IN THE HOOD TO PROPERLY VENT EXHAUST GASES.  MOISTURE CAN EASILY GET INTO THE DUMP TUBE AND CAUSE PROBLEMS, BE SURE NOT TO STORE THE CAR OUTSIDE WITH AN OPEN DUMP TUBE OR DRIVE IN THE RAIN***

Install Tip: Removing the studs on the turbine housing will allow for a much easier install of the new housing.
