Just finished installing my Fullsac True duals conversion along with the 2" baffle replacement cores. I had a bit of a time grinding down the weld beads but they slid out after a bit of coaxing. The sound is just fracking awesome. I had a friend riding behind me tell me that they sound bad azz when letting off the throttle! Oh and that sound of a true dual system! I need to find a straight 22-24" heat shield as the reuse of the stock ones look OK but would look better with a straight seamless one!I also installed a set of XIED's and there is significantly less heat coming off the pipes in places that matter.
