well i bit off more than i could chew this weekend in my 95 vette, i raced one of those new subaru wrx's. this guy smoked me off the line and pulled away from me until about 80 mph(about 5 -6 car lengths ahead. then i couldn't catch him and he wasnt pulling away anymore. we did this all the way to 130 mph. when we got into town he pulled in to get gas and i asked him how he had modified the car and he said all he had was a catback exhaust and a k&n filter. i will stray away from these things from now on.
