any loud exhaust will usually have a rasp at high rpm when u rev it, my car has a rasp with the cutouts open, the main thing you will gain with no cats is a small bit more power, and alot louder sound

i did, cant hurt to have a little more horse under the hood, and think about adding a set of cut outs on that car with the headers youve got they will sound great and should add a little extra horse!

high flow cats vs no cats is not that much differents in power, but no cats are cheaper,LM1 loud no matter what.

I would opt for no cats. I have never run them on any of my f-bodies.
