I can’t get any exhaust. Even stock when it revs high its audible enough for people to stare n think you’re doing it on purpose. BMWs have a bad enough rep, I’ll leave the noise for infinitis, hondas, stangs n of course - Harley’s . New exhaust for performance is one thing but for added noise seems a little obnoxious nowadays. I wish these aftermarket ones did have like some silencing mechanism for when you do not don’t want it to be loud. Of course that’s just my opinion and the majority of anyone who has to hear it
