I think you'll loose too much on the low end to make it worthwhile, plus-making the 3.8 louder is not better imho.

If you still have the stock cat setup you have 4 of them, ditch the rear two, then you're still legal cause you will still have 1 on each side and leave the sensors before and after the first set and you wont throw any codes.

if i delete the 2 rear cats will it make it sound more raspy? i know once i hit 3500 rpm with my straight pipe it kinda sounds a little obnoxious. since the muffler and res delete i found i lost some power but gained a little on the top end.

I see that you are i n CA. So am I. I wouldn't recommend touching the cats at all. You need to finish the dual exhaust (some new/used flows are about best for 6er's) out the rear(tailpipes, my old barracuda was dumped at the axle, hated it, gets annoying after awhile) and call it done. Strict rules here, but it is what it is.

Ooh I didn't see your state. Yeah you can't hardly repaint a car without getting an illegal mod ticket.
