I put black mufflers from a 2015 on my 2013 that had chrome. A bit Louder at idle. But much louder when going through the gears normally.
At highway speed you can hear em good. If it were any louder I would call it dronny.
Ive rode behind an F6B with two bros exhaust. Sounded good. Not really louder than the black ones but better sounding. Growly.
