The emissions issue will depend on how it is tested. If it's a simple OBD plug in test, than passing should be no sweat. If the emissions testing is done with a sniffer, then passing will depend upon state standards. I don't know how much work the secondary catalyst is actually doing, but I would expect to see some increase of unburned hydrocarbons (I doubt it's a significant increase) as a result of removing the secondary cat.
Mid pipes should not cause a CEL as the secondary cats they replace are unmetered.
WRT fitment issues, I would not expect any aftermarket part to fit perfectly without some degree of fettling. Sometimes things fit perfectly, sometimes not so much...
