i have a buddy with a 02 mustang gt. what do u think he should run 1/4 and 1/8 mile with these mods. h-pipe with no cats, flowmasters, underdrive pulleys, cold air induction and nitto drag radials.

 

low 14's high 13's?

 

No gears? Maybe 13.8 - 14.1 or so. Locally most GTs run in the low-mid 14s, and one with all the mods you mentioned plus 3.73 gears and a real good driver is running a best of 13.6. They just aren't that fast of a car, nor do minor bolt-ons do very much for them, other than ensure the SES light comes on often.
