Elvin315, Sorry about the late response on my 4/1. I got the idea from Jim snyder. I am running his original idea of lopping off the left side spiget and having it welded up. He has great pics on his photobucket. He now is doing the ontario pipe set up I will probably do one of these in the off season to get a little more flow. I am running a Delkevic muffler its a little loud wihtout the sound db killer inserted. I am rinning a k@n with 1 3/4 foam cut on Steve,s 2 min mod plus he went through the carbs and Steve,s exhaust gear. I have enclosed my Dyno Pulls, She laid down almost 93 horses and decent torque It runs great. Anyway hope that helps. I also had the entire system Ceramic coated and installed heat transfer protection from Summit Racing to the inside of the belly pan to keep the heat off the plastic it works out perfect I used it on my Bandit 1250. Hope this helps feel free to contact me for any questions.
