If or when you have time could you take some close up shots of the bracket you made for your slip ons.If you want to save money and do the slipon thing, the best thing is the JC Whitney mufflers for $60.00 for both and then all you have to do is make a real simple bracket
to keep yhe top muffler stable, cost of bracket is less than $5.00 in metal. I did this mod on one of my VTX bikes, the sound for me is just right, no need to rejet, just do the Scar mod and take off the pair valves and put on block off plates. If you need any help or more info, just let me know. Here is a picture of my bike with the slipons.
