Pat, I was thinking about dumping out in front of the rear tire so that the exhaust would blow the pavement. My theory is that when I'm taking off from a stop, it would clean the road a little so i could get better traction. Like I said it's a "theory". It could backfire and spray moisture instead. The idea backfire not the car. I also like the idea of dumping before the axle because less bends means better flow.
