You can lay your hand on most carbon fiber mufflers after riding the bike...but 2bros burst into flames!
I never liked 2bros.
There was a pair of their cf mufflers on my B-king when I got it.
I liked them even less then.
If you like obnoxious droning at cruising speeds(without spending another $100 for quiet inserts)...that may randomly catch fire, then 2bros is for you.
Acropovic makes great carbon fiber, and Yoshimura's is pretty good too.
