I have a set of HD take offs on my VX I cut the pipes off at the pipe muffler joint , with a saws all and welded them on. To cover the unsightly weld I added a couple of chrome heat shields that mount with a hidden hose clamp. It seems to pull a bit better and certainly sounds better. My stock mufflers were pretty beat , besides I don't care for the styling of the VX mufflers. This solved my problem for under $50.oo!
