I was on the highway crusin and seen a 4door ricer accord(muffler). I passed him up at a normal speed, he then got on my ass, at which point i floored it, he was keepin up for a few secs, but i then pulled away from him at about 110. Then about a min later a probegt(CAI) come flying outta nowhere. He was in front of me but the distance btwn us stayied the same. At first i couldnt pull to the side because of cars in the other lane. After there were no cars, i pulled to the other lane and started to gain on him until i passed him up. Both of the racers where driving solo and i have another body in the car.
