UPDATE: Once I started to put heat shields on found they shorted me l black clamps for shields. I see their attention to detail on the little things has not gotten any better. Love the sound and performance of the pipe but they still **** people off with this kind of stuff.

Why would you say that? They've been making TH's for decades and ppl were putting them on 80ci EVO's (and probably earlier, but thats a far back as I go) and they have always been among the top if not the top performers...

It's quite the opposite and has been proven many times. M8's with the 4V heads really do well with a 2 into 1 versus a 2 into 2, especially down low in the powerband. Add a cam, and off you go. Go check out FM University. They have done a crap load of cam and pipe testing and the numbers are better for the 2 into 1 systems as a whole.

Go watch any Sons of Anarchy episode. Most of the Dyna's on it had TH's and I once read that they made sure the audio recording of the bikes were authentic and not enhanced with special effects. Probably to help HD sell bikes...
