What exhaust? :icon17: Test pipes with cutouts.

Advanced group is a whole different animal. My club that I typically run with in advanced are mostly racers testing and tuning or people who have been doing it for many years if not decades. Fastest way to learn car control is track in the rain. Lower traction on the tires through cheap tires and higher pressures will do too for some extent but not really. Seat time with an instructor/pro will do as well but that can get pricey. When it rains on a track day I can't be happier, you'll learn a lot about how your car handles while being at a lower speed and everything else being the same except for a few minor things. The though being if you do seriously screw things up and go off and hit something the speed/energy/damage will be exponentially less then if it was dry.
