Well i have to be heard on this, elevation might play a role in this, but if anyone remebers my old sig, I had at one time: just removed silencer, box with knN, all cat cvters, 3cbr mufflers, aluminum d/s, going 14.1's.
with electric fan and swaybar removal, i nailed a 13.91 on little tires in sig with a 2.0 60', i could have made a 13.80 easily i know, now with my h-pipe and SFC's, and my friends e,t, streets, i ran 13.6 on a very humid night, and the tires were to low psi bogging, with more air in them i could have cut a 1.7 and seen 13,4
but unit i dont believe your car will trap more than 100mph, maybe 99, but being you can stay in 3rd you will be close, but with stock h-pipe i dont see it happening, plus the stock cluch fan really drags a stang down on the topend. your looking at g-teck maybe.
