Aftermarket Gears
I bought an used s2000 from a honda dealer in august it came with some mods(coilover,intake) and I think it might have some gears is there anyway I can tell without pulling anything apart?

yeah have him bang on the rev limiter for a few seconds to make sure he's really tapping out the revs...
but, if you really want to know what gearing you have use this page for your calculations...

^the top speed W. gears will ONLY work if you have a speedo calibration. if you dont the speedo will just give you the wrong speed
idk if you can do it on the S since it has IRS, but if you spin the diff and count the rotation of the tires you'll have a good idea. (it worked on my solid axle camaro).

look at the tranny and see if there is any wires spliced into the speed sensor. If so you most likely have aftermarket gears with a speed calibrator. Look at the diff itself to see if it looks like it has been opened before. Same with the driveshaft/propeller shaft. Look for tampered bolts.
****If you don't have a speed calibrator installed****
If you have a friend who has a stock vehicle and match speeds on freeway. Do you have a GPS? If so use that and try to check actual speed versus your dash read out.
You can try the one tire rotation compared to driveshaft rotations also like mentioned above. This only give you an estimate. Gears come in 4.10, 4.30, 4.40, 4.44, 4.56, 4.57, 4.77 ratios
Other than that you have to take the diff out and count teeth.
