you may gain across the whole band or not, no one knows how our engines takes to diff. exhausts since its so early. you could dyno before and after and post it, that would be nice.

either way i know itll sound plain bad arse. 300 isnt too bad considering they are installing it. if you install a cat-back system (all bolt on) yourself you could buy a gibson (alluminized steel) for $50 more but its a single outlet, im not sure on the availablity/pricing on the duals. duals will surely be louder and throatier if intimidating hemis is your fancy.
