Every once in a while I see this guy with a cool silver M5 driving/speeding on my local 267 and 495. I'm sure the only mod he's got is the exhaust, which does the V8 justice. Anyway, back when I had my '04 WRX (HKS Carbon Ti), I knew I had zippy chance, but now that I have an STi, I noticed I was as fast, if not slightly faster than his car (35-80 mph).
Could someone confirm if this is true? I'm pretty sure had the road been stretched a bit more, he could have done some damage - who knows - I don't really 'race' much, but I'm pretty sure these M5s trapped at around 105-107, which isn't that much more than the STi.
