Cut the flange off your cat back, slip that cat over the 3" pipe, then weld or clamp a 6" pipe to your y-pipe and you're good to go.

Well, i guess i should explain that i'm going to "configure" (so to speak) the Y-pipe to end up at 3", cause right now it is 2.5 So i'm gonna weld a peice onto that making it 3" into the Catalytic Convertor, is the 6" weld still necessary? and for which set-up? (Certain Convertor?)
