Finally got my AMS 35r from ams today , and i was syked to install it. When i got to installing my downpipe to my test pipe i realized that the AMS downpipe that comes with their kit is a 3 bolt flange and my helix test pipe is a 2 bolt flange along with my greddy exhaust. My question is, what the hell do i do? Worst comes to worst i would have to buy a new exhaust (SUCK!). I can have a guy cut off one end of my test pipe and weld a 3 bolt flange to it, but that would cost me a pretty penny as well. And not only that, but they wanted it to be 3 flange for a reason. What should i do? Any suggestions?

I had the same problem trying to adapt an AMS catback to a Works HFC. Just take it to a muffler shop and have them weld on a different flange. You might have to source a new flange yourself.
