gearing question?

i just bought a 50 th anniversary 2003 a4 3 weeks ago.. and i dont know what is the stock gearing on this car... is there a place where i can find it on the car...

i am also new to this forum.. lots of usefull info...

i am going to the 1/4 track tomorow with it .. to get a baseline before i wake the car up a little bit...

there is only a k&n filter on it right now with no cats..
i am pretty sure i should have the 2.73 but i was reading on this site that some c5 had the 3.15 i thinks...

help appreciated..
thanks

GU2 = 2.73 Standard Ratio
G92 = 3.15 Performance Ratio
