This 3″ O2 housing is designed to work the Borg Warner 6-bolt outlet turbine housing. It is to be used ONLY with our DSM T3 bottom mount exhaust manifold. Made completely from 304 stainless steel! The flanges are CNC machined from ?? material and are surfaced after welding for a leak free seal.
***NOTE: due to the tight radius of the bend you will need to install a stud in place of a bolt for the bottom mounting hole.**
