I picked up an exhuast and tp but I dont think I'll be using it. Im not sure if its a 60 or 70mm (maybe Mike or Erik could help me out on this one) but its stainless. My buddy has it at the moment because he was trying to match up the triangle gasket (he works at a gm dealer) it has an anti-fouler on it already also. just seeing if theres interest here before I post it up in the fs section It looks practically new.
