Just put new Rinehart slip-ons on the Chieftain. Man, they make the bike sound so much better. Got a nice deep rumble at idle and sound really good going down the road when you get on the throttle. J&P Cycles had a special no-tax sale this weekend and took advantage. Ordered them Saturday and they were in my driveway yesterday. Incredibly fast shipping. Got them put on last night and riding today.
