i have bought a used 3 in. atr downpipe from another board member.it came with what ive found out seems to be an old applied technologies wastegate.i dont know if it works or what size it is.but with the amount of money i have into my car i dont want to take any chances.i want a 46 mm gate.do they make wastegates that bolt right up to this pipe(two 2 bolt flanges) or do i have to fabricate to accomadate a different mounting style setup? thankyou in advance,ed
