Sounds pretty good, but much too loud. The hi-flow cats wont shut it up a whole lot, OEM ones would, but its still restrictive OEM.. And wow I thought I had the loudest Magnaflows around here.... hmm... thanks for stealing my thunder
I sure wish my idle sounded like yours, keeping my acceleration sound/volume as is.
It does sorta sound like your exhaust has no X pipe which could calm it down and increase your performance numbers some. And running your tailpipes out to the rear would quiet it down a tiny little bit for inside, outside wont change too much but it'll be a hint quieter.
