Can any one tell me when you use the certain pipe adapters.We mainly run a 1/3 mile track.Which one would we use,short, middle size ,or the long one?thanks

depends on the length ogf the straights and the gears you are running. what track are you running?

Clinton County mainly. thanks

clinton's a top end track normally, you need the speed down the straights. use the shortest for your top end, if it lugs a little in the corners, try the middle one.

Thanks for the response HAWK. I'll give it a try. I've been using the long one.

the long one is good if you run at selinsgrove or millville where getting off the corners is key. good luck and have fun.
