just a note i have 2 friends out here with 05 + v6 mustangs and both with dual exhaust, well they both still have a different tone then any v8 by far but one i can approve of so i'll ask him what exhaust he has and the other guy has a gt front and rear end due to an accident and he said the set ups are extremely similar so shouldnt be too much of an issue... i'll send ya a message if i talk to them or if i have my video camera i'll get some clips of their exaust for ya :)
some of you that go to firebird will probably have seen the red v6(GT front/rear end) he runs at firebird most every weekend, license plate says "its a v6" so im sure youve heard his?.
