Upper muffler
Upper muffler, Triumph part 70-6974 (alias E6974), later superseded by 70-6974W.
This is the upper muffler listed under Triumph part number 70-6974, also known by its earlier alias E6974. It shows up in the parts-book figures for exhaust pipes and mufflers, including entries tied to the T100C and TR6C, and in a U.S.A.-market exhaust pipes and mufflers listing. Catalog appearances run from 1967 to 1968.

The factory later replaced this number with 70-6974W, so if you're working from a later parts book or a bike built after this run, that's the number you may see referenced instead. Both numbers point to the same physical muffler.
We don't have more detail on this one beyond its place in those exhaust figures. Call the shop and we'll confirm fitment before you order.
