And carbon fiber mufflers put more heat out of the tailpipe, vs radiating off of the muffler, you can grab one bare handed with the engine running...you don't want to to hold it, lol...but a Big differnce in heat around the bike and your leg, like a full cf Akropovic, putting most of the exhaust's heat behind you, vs a Brock AlienHead...cooking your right leg and melting your boot at the red light...
lmao
