I ended up delteing my resonators...not the cats. Still have the stock exhaust.

IMHO, it did not make a lot of difference in sound. It is slightly more raspy, but really not a big difference at all.

I felt no difference in power at all. Hell, they are basically just a straight pipe with some hole in the walls for baffling sound. No restriction for flow in them, so I would not expect any hp gain or loss.
