It had an exhaust im not sure what else but it was on the highway from 3rd gear and i pulled a car on him until we ran into some traffic. Are they fast?
I've seen some stock E36 M3s run faster than an MS3 while others run slower. Most magazines tests showed 0-60 times in the mid fives, while 1/4 mile times were in the low 14s. The cars respond very well to the Conforti CAI/exhaust/chip combo.
The 2001-up(E46) M3s run to 60 in the high fours and do the 1/4 in the high 13s.
