Panhead Exhaust Systems For 1948 - 1964

1-3/4" Exhaust Systems For 1948 - 1964 Panheads
Muffler pipe sets with an outside-the-frame front pipe, and a rear pipe that routes in front of the transmission, or drag pipes with an over-the-transmission rear pipe, guarantee classic style and a throaty sound.

These muffler systems have slider channels, and will fit all 1948-1964 Panhead engines in rigid frames with mechanical brakes. Also fits some swingarm frames.

721TM 38"-long Tapered muffler set (shown below on bike)
421R Rear heat shield for Paughco #721 series pipe sets (shown below on bike)

Special Notes:
1) Drag pipes are not recommended for use on the street.
2) These pipes have less ground clearance than original equipment and may scrape on hard right hand turns. Do not use these pipes unless the front end is extended at least 4" longer than stock or serious injury may result.
3) See page 247 for P-clamps and frame rail clamps to install these pipe sets.
