I have this exhaust on my 2017 Low Rider S with the 117 stage 4 kit. This setup literally stops people and makes them stare. My only complaint, the lack of exhaust shields. Especially on the rear pipe. Your leg begins to fry at a long stop light or waiting in traffic.
thats rusty butchers bike. i believe you can search it here on youtube if you enter "rusty butcher fat bob" you can find a list of parts on it on his website if you search "rusty butcher bikes" as for the fairing i believe its a burly brand "touring sport" tall fairing. it costs 300 USD on burly's website. probably cheaper on revzilla, dennis kirk and other sites that sell club style harley parts. it should be noted that he has a front end witch is not stock to this bike so it may not fit the 2018 fat bob with out switching at least the headlight or maybe whole front end.
