Panhead Shotgun Exhaust Systems For 1958 - 1964

1-3/4" Panhead Shotgun Exhaust Systems For 1958 - 1964 

These complete systems fit 1958–1964 swingarm frames with electric or kickstart and swing-out kicker ONLY. They will not fit with a large FLH battery. They all have slider channels so you can use a Paughco #718J bracket (sold separately) to install the rear pipe (see page 263). A heat shield for the rear pipe is highly recommended.
