gti vs subaru sti

I was driving home from class today on Rt 30 East, and what appeared to be a 1999 era Subaru STI pulled up behind me, it was debadged and appeared to be modded. Anyway, he was riding my ass alittle, so I decided to give in and play. My MKV has an APR Stage 1 tune and an SRI by the way. As soon...
