BSA Exhaust pipe (left-hand)
Left-hand exhaust pipe, BSA part number 70-9127, from the engine top-end exhaust pipe figures.
This is the left-hand exhaust pipe listed under BSA part number 70-9127. It's a BSA part, not a Triumph one, despite showing up in Triumph-adjacent parts references from time to time - the catalog figures for this number sit under CYLINDER BARREL, EXHAUST PIPES, VALVES, which is exactly where you'd expect an exhaust header to live on the engine.

Catalog appearances for this number run 1969-1970, and it shows up alongside companion pipe numbers in exhaust sets for that era. If you're sorting out a matched pair for a twin-pipe setup, make sure you've got the correct left and right numbers together rather than assuming one will do for both sides.
Our records on this one are fairly thin beyond the figure listing, so if you're trying to nail down exact fitment to a specific machine, give us a call and we'll confirm before you order.
