Front Exhaust Pipe Clamps

The two clamps for the front pipe mount above the sidecar loop on Knuckleheads and below on Big Twin Flatheads. Therefore the kit for 1937-1946 Knuckleheads includes a 1-1/8” small clamp and the kit for 1937-1948 Big Twin Flatheads and 1936 Knuckleheads includes a 1” clamp. When the factory introduced the accessory flex type pipe covers in 1947, the clamps for the front pipe were changed to a P-design for OHV models and mounted below the sidecar loops.
