What Straightflow states

Straightflow lists it as compatible with BMW B46 and B48 engines, with a machined mating surface for accurate alignment with the turbo outlet.

Straightflow says the stainless construction gives heat and corrosion resistance and a clean welding surface, and that the precise machined sealing face gives accurate bolt alignment and proper sealing once welded in. It recommends professional TIG welding and states the part is a fabrication component, not a direct OEM replacement.
