Just an FYI I had to install cats after I failed inspection on my AA exhaust. I was worried it would restrict the sound and a tad bit of performance. Performance not sure I wouldn't be able to tell either way. The noise was exactly the same, I'm still heard from 1/2 a mile away. I kida wish it was quieter now, oh well good problem i guess. You should save your money and not buy/install the cats.

Edit-sorry didn't see it was your stock exhaust. You should have just bought something like AA. You won't have to worry about rasp then! More like making little children afaid for their lives from the growl.
