I'll have to post pics but I just hung a set on my moder and they rock. The center plgs angle away from the tubes perfectly and the end plugs angle right AT the tubes. but the tubes loop out so far that it'd be easy to fit a 90 plug boot on them with 1/2-3/4" to spare (haven't measured). Again I'll mock up with a plug and picks (after work).

PLUS the Flowmaster ball & socket adpters that Moparts member whiplash suggested (cut off the 3", 3 hole collector style plate and weld on a 3" tube to 2-1/2" exhaust pipe ball & socket connection/reducer) will allow me to tweak the collector if needed. I really intended just to use these for a run-in stand but they don't look too bad.
