This Punishment Racing O2 housing only has ~20 miles on it and is in great condition. Right now I am cleaning it up and getting ready to put a new layer of paint on it. that is the reason that the paint looks weird. Uses a 38mm Tial (2 bolt flange) wastegate. I have one of those for sale too. Also including 4 brand new O2 housing OEM bolts. It usually uses 3 bolts and a stud, but I like to use just the bolts. You can do what ever you want.
