Exhaust Pipe Diameter on Stock GTS?

Hey, does anybody know what the inner diameter of the GTS's exhaust pipe is? Is it 2.25" or 2.5"? Is it the same diameter from the downpipe to the resonator?--besides the CAT of course...I don't care about what's after the resonator...Thanks...

I asked around and a few people said the stock piping diameter is 60 mm or 2.36 in. So going from 2.36 in to 2.5 in piping is a 12.2% increase in flow. Essential for nitrous users but I don't think it will help that much for N/A.

thanks Jae...
so if it's not 2.5" inner, do you think it's 2.5" outer? Just want your opinion.
