1-3/4"  Panhead Over The Transmission Exhaust Systems For 1948-1964 

An outside-the-frame front pipe, and a rear pipe that routes over the transmission, bring a modern style and a throaty sound to your 1948–1964 Panhead. These systems will fit rigid or swingarm frames, but will not fit with large FLH battery. They all have slider channels.
