Thank you all for your help with your help on confused about exhaust. I went with Sparks
I have a other issue i would love to have your advice on. I would like to get a little more torque for racing the hill at the dunes. I changed my back sprocket from a stock 38 to a 40 and I drop down one in the front. It seem to help, howevere it still seems a little slugish on torgue. Short of having a big bore kit I have tried all that I know, ported and polished, Hot cam, FI controller, Power programmer, K&N, hot coil. Am I approaching this in the wrong way?
