T120 SILENCER SET LONG 63-65
Long-style silencer set for the T120, cataloged for 1963-65 unit-650 twins.
This is a T120 silencer set, the long-style mufflers listed in the catalog for 1963-65. It's cataloged as a pair, matching left and right, and sits at the back end of the exhaust pipes where the header pipes terminate under the seat and rear fender area on the unit-650 twins covered by this figure.

The part shows up in the catalog under a few numbers over the years - you'll also see it referenced as E4949 or W664 in older books, and the factory eventually carried it forward as 70-4949W, which is the current version of this same silencer set. If your parts book lists one of the older numbers, this is the part you're looking for.
These fall under the exhaust pipes and silencers figure alongside engine unit fittings and footrests, so if you're replacing the whole exhaust system it's worth checking what else in that figure needs attention while you've got things apart. Give us a call if you're not sure which version your bike takes before ordering.
