I like the LTE duals. look, sound, and perform good. I don't know what's the "best" but these are good.

Hey Brother you know what mine sounds like,  the "best pipe" would escential be based on the type of riding
you plan to do. some pipes will sacrifice bottm end for top end speed other will do just the opposite, I like the White Brothers E series 2 it pulls up through the power band and it is not Obnoxiously loud.
