Can someone help me out and tell me what size v-band I need to connect the exhaust housing and center cartridge. I don't know if the turbine size matters but its a 83mm and t-4 housing.
I just went thrue this same thing on a s400 used as a secondary. Search eBay for billet exhaust flange s400. I can't remember the companys name but they're out of fl and shipped fast. The t4 housings were all the same from what I found and it was made for 4" pipe. Quality piece.
