Got a little bored last night hanging out on the main drag near me, and decided to mess around with my friend in is 2005 M3. The M3 has intake and exhaust. Went from about a 20 mph roll in first gear. We went on the third horn honk, which he jumped by about 10 feet and I still managed to take him by about half a car length. We are going to go from a stop soon and I will let you guys know the results.
