JMF Sheetmetal O2 housing

Replace your restrictive OEM cast O2 housing with our free flowing custom 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 3D contoured to match the shape of the turbine housing for a smooth transition. Each unit comes with a stainless steel gasket.

Also available as an external dump for those lookin for some increased volume :)
