When I was mentioning the Y-pipe I meant the whole thing, from cats down to the single exhaust flange going to the muffler.

If you use the 94-98 style use a 2 1/4" flange, if you use BBK's are are for 99-04 then use a 2" flange.

Call BBK and ask them about their collector to flange size, also ask them if they ceramic coat the inside of their headers, some companies do.
