Knucklehead Shotgun Exhaust Systems For 1936 - 1947

1-3/4" Shotgun Exhaust Systems For 1936-1947 Knuckleheads
An outside-the-frame front pipe, and a shotgun rear pipe that routes over the transmission, bring a modern style and a throaty sound to your 1936 – 1947 Knucklehead. They all have slider channels except the 34" drag pipes, which can be installed with P clamps. 


729D34 34"-long Slash Cut drag pipes (use Paughco #725D clamps to install)
729D40 40"-long Slash Cut drag pipes (shown below on bike)
729DGM 38"-long Goose Cut muffler set
729DM 38"-long Slash Cut muffler set

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.
4) See pages 349-353 for photos of the heat shields for these pipe sets.
