Exhaust pipe—L.H
Left-hand exhaust head pipe for a 1972 Triumph 650 twin, part of the push-in style exhaust set.
71-2636 is the left-hand exhaust pipe out of a Triumph 650 twin exhaust set, cataloged for 1972 under the alias E12636. The parts book places it in the EXHAUST PIPES AND MUFFLERS figure, and the catalog data ties it specifically to the 1972 model year rather than a broader run.

1972 was the year Triumph moved to the push-in style exhaust header on the twins, a design that mates to a specific cylinder head configuration rather than the earlier spigot-and-adaptor arrangement. If you're sourcing a replacement, check what your head takes before ordering, since the two styles are not interchangeable.
This is the left pipe of a pair — you'll want the matching right-hand pipe (71-2637) to complete the set. Give us a call if you're not sure which style your head needs.
