I have a 07 Street Glide and have a Thunder Max and installed just the Rineharts Slip on mufflers. I want to go with a true dual setup and just keep the Rineharts mufflers. I was going to buy the V&H true duals and then just put on the Rineharts mufflers, i was thinking about buying the Rinehart true dual set up, but it is cheaper for me to get the V&H TD since I already have the mufflers. Any difference in the True dual Rinehart set up to jsut puyying V&H td and rinehart mufflers, sound or performance. Please help!
