I have a 99 fi Road King with a well built engine. It has Samson true duals and SuperTrap slipons. I am very happy with the sound of the SuperTraps but don't like the fishtails. The other tips for these slipons are also not the look I am after. So my ? is are the SuperTraps good performace mufflers and should I be less vain about the looks or are there better performing slipons?
