i was driving on the way to north county mall today in escondido when i see a yellow mustang in my rear coming up next to me at the stoplight. i see all the mach 1 emblems and such. 300 hp right? well he asks if i want to go, i say sure. he had 1 passenger, i had none. the light turns green and i take off slow then punch it. obviously i take it off the line. it suprised me, i just kept on pulling on him. i could hear his engine slowly fading away in the back. we shut off at about 105. i asked the guy what he had. he said magnaflow exhaust. didnt even ask what i had just waved and took the onramp to the freeway. i am happy to say that a bone stock STi can hang with a mach 1. i wouldnt mind having a mach 1 though.
