I am trying to purchase an OBX header for my r53 and am having 0 luck finding one. There are three online vendors all linked back to the same phone number for OBX racing in CA and he says theyre out of stock and doesnt know when they will get more but 30-60 days was his hope. Does anyone know where there are any in stock? or used? I cracked my precat and ordered a Borla aggressive exhaust and I am just waiting on this header to fix my mini.
