Just the tip.
Wow is all I can say. This tip gave my 2019 Yamaha bolt R-spec it’s balls lol. It’s mean it rumbles and it’s a beast! The o2 sensor bung is nice but currently running it with a o2 sensor delete from Taiwan
It's just the tip. it might get a little loud.
Direct bolt on tip. no need to cut up your old muffler because it has the o2 built in
