Just curious, I know Long Tube Headers make a little more HP but is there a sound difference between getting them or getting an O/R H-Pipe? Also I know MAC are about the only LT Headers that fit automatic, is is the same with O/R H-pipes?
i would have a hard time believing that are you sure? I think flowtechs fit autos...only the headers would be affected by the transmission i believe all the midpipes are the same
