i kno this thread dont go here but i need a quick response and everyone hangs out here haha. what size PVC do i need? i saw a vid that used the bell end of a 3 inch pipe so it was around 3.5 inches. some help me out?
its in now. i didnt bore out the hole, i shaved down the pvc lol. with a circular saw. and i didnt have a vise so i bungee corded it down to a table....its amazing the things youll resort to when you dont have the proper tool. i took it around the block and it felt the same, i can hear it more at higher rpms, ill have to plug in some numbers to see how big of a difference its making. all in all im not dissappointed witht he 15 bucks i spent on it lol
