One Cat in the I Pipe? currently running LT's, catted Y (two cats), and magnaflow catback....just wondering if my car will get any louder with just one cat in the I pipe and will it still have no rasp or do i need the cats before the merge so get rid of rasp?
A single cat will not flow anywhere near as well as the two you've got right now. You'd be choking your exhaust if you installed 1 in the I.
It's possible to make a ORY that has little to no rasp. I've got one. I think it mostly has to do with the design of the merge.

Cats need to be as close to the engine as possible in order to function properly. A setup that many people run and sounds very good is an off road y-pipe with a bullet type muffler in the I-pipe (bullet, sweet thunder, spiral flow). The setups I've heard like that are pretty loud but the muffler gets rid of almost all rasp.
