That part looks familar in design to one I remember seeing construted 5 years ago

. It was a great design then, and a great one now. There are only so many ways to make a 02 housing on a dsm! I am assuming that is for a tial 38mm, does it clear the PS pump on a dsm? I know of one that didn't quite clear well, this one looks good.
Looks very good guys, I'd recommend grinding off the vibrant name on the flange, otherwise they look like a Vibrant 02 housing, not a MAP 02 housing.
