Well, just bought a stock downpipe from someone on SupraForums. It looks to be the right part, and seems like it will bolt up great on the y-pipe side. The only problem is I can't see anywhere on my stock exhaust where it will bolt up? The place it seems like it would go has a 2-bolt flange, where as the 1JZ downpipe has a 3-bolt flange on both sides. So, I guess my question is, where did you guys bolt up the downpipe to the exhaust, and also, was your downpipe a 2 or a 3 bolt flange on the side OPPOSITE of the y-pipe?

Thanks guys
