I asked this question awhile back; Spohn's subframe connectors fit with the Hedman y-pipe. I'm not sure about other brand y-pipes, but they'll most likely fit as well.

I'm getting some binding with 1.75" SLP headers/Y-pipe combo using SSM subframe connectors. I'll have to take it to the exhaust shop soon to drop the pipe about 1/8". It only rubs under WOT when the engine torques over under load.
