RE: Dont worry about all Mustangs...
the SRT8 is supposed to be doin low 13's bone stock,not sure I'd wanna do any suspension mods though from what I've read in Car&Driver and a couple other mags,but with the exuast and CAI it should get 13 flat or high 12's easy.I should be getting mine Tuesday and there's a track not more than 30 minutes from me in Bithlo,Fl. so I'll let ya know for sure in about a week.
