Alright, what the hell type of flange is this? And where can I get o2 housings or dp's for this particular flange. this is the flange that bolts up to the turbo exhaust side (between turbo and dp), except I cannot find out what this type of flange is called. I also cant find where I can buy a 02 housing for this type of flange. Any help would be greatly appreciated, thanks!
