Exhaust spreader tool make spreading the exhaust fingers easy and uniform. I purchased this new from scooterwest.com for $20. The graphite bushings are needed when installing the exhaust (like a new exhaust or after installing a rear tire) or when the exhaust starts getting loud (the bushings have a tendency to break down over a few years and the exhaust gets louder).
I include three new exhaust bushing, tho one was installed but removed before I ran it.They are $17 each.
I show the bikes it fits according to Scooterwest.com in the photos below
$45 for everything including shipping.
