While looking at the exhaust menu for my 2007 Ultra, I saw asymmetrical baffle design Jackpot Mufflers, other slipons with the same size baffle, 2 into 1, or true duals. Looking at these choices I am going with the Dyno tuned asymmetrical slipons since I am a fan of 2 into 1 exhaust systems. Can anyone give me advice on some of the other choices and the advantages? When did they come up with different size baffles and what do you benefit?
