CUB SILENCER LOW LEVEL
Low-level silencer for the Triumph Cub, also listed under the older part numbers 37-0803 and W803.
70-3928 is the low-level silencer for the Triumph Cub. This is the muffler that mounts down along the frame rather than up high, and it's what shows up in the catalog under this number for that model. The older parts book form of this same part is 37-0803, also seen as W803, so if you're working from an early Cub manual and the number doesn't match what's stamped or listed today, that's why.
