thats what mine sounds like with a high idle.

I would go with 3" true duals w x pipe and dynomax bullets it will sound like this.

well im actually gonna do a x-pipe right from the headers and just extend it a little from the X and just dump it. I want the scavenging i get with the x-pipe but since its more "race car" i dont want the added weight weight from mufflers. And noise isnt a factor with me. Its a "race car" not my DD

Its going to be nice to look under the hood and not see the PS and that bulky alternator on top, plus looking forward to seeing how much HP it frees up.

nice... got any pics of ur setup you made? i just cant justify buying one off some guy making them for like 450 or something. if i got a couple ideas to try and fab something that would be cool. I HATE the look of the nasty ol alt on top and moving it down to the bottom would create some room for a hair dryer
