Hey guys, I bought my car last spring, its an 03 GT. Mods done are Bassani headers, bassani exhaust, BBK TB, BBK CAI, Steeda Underdrives, and a few other things. The guy i bought it from was a dealer who took it on a trade and didnt know much about the mods done to it. I'm going to put gears in it, probably 4:10s, but i was wondering if it has gears in it already and he didnt know. My RPM's at 75 mph on the highway are right around 2100 or 2200. Is that normal for stock gears, or do you think theyve already been done? thanks!

Yup that sounds like stock.

Cliffyk's RPM/Speed chart thingy is so useful for things like this and especially for peeps wanting to know what RPM's will they be at in different speeds in different gears with new rear end ratios:
