I have SLP 1.75 headers and want to order subframe connectors, but I don't want to have to modify either.

You shouldn't have to modify anything. Make sure you get the weld-on SFC's since the bolt -ons won't clear the SLP Y-pipe

STILL Looking For:

I don't have headers, but the Spohn SFC's did not change my exhaust clearance at all. & their crossmember design increase the handling advantages weld angles are "interesting" to say the least, heh.
