1¾" Drag Pipes For 1970-1984 Shovelhead Engines With S.T.D. Cylinder Heads

These 40"-long Slashcut drag pipes are specifically intended for use on Shovelhead engines with S.T.D. cylinder heads in rigid or swingarm frames. Because of the unique 3-bolt exhaust flange incorporated into the S.T.D. heads, they require special exhaust systems. We have taken some of our most popular drag pipes and modified them accordingly, and then put slider channels on them to ease installation. Heat shields for the rear pipes are highly recommended.

These 40"-long Slashcut drag pipes are specifically intended for use on engines with Panhead or Shovelhead lower ends and S.T.D. cylinder heads.
