I have a 2000 road king classic with stock head pipes
And supper trap slip ons wanting to do true duels thinking of going with the fullsac true duel head pipe kit anyone know anything about it thanks pat

 

I know I am going to hear about this but I would never run true duals. Do research on why all motorcycles now have the two pipes connected or even engines with more cylinders including cars.

Good reading.

I ran a Fullsac kit for a few years and was very happy with them. However I have since installed a 2-into-1 and the improved low/mid range torque, plus much sweeter running, are why I won't be going back to true-duals.
