BSA Exhaust pipe — left
A left-side exhaust pipe, part number 70-2580, from the cylinder barrel and exhaust pipes section of the parts book.
This is a left-side exhaust pipe, part number 70-2580. The parts-book listing places it in the cylinder barrel, exhaust pipes, and valves section, which tells us it routes exhaust gas away from the head on the left side of the engine, but that's about as far as our record goes.

The manufacturer tag on this entry points to BSA, but that tag is a heuristic and we don't have a canonical description or figure title that names a specific model or bike to confirm it one way or the other. We only see this part number appear once in our records, tied to 1971, so we don't have much more to draw from.
Given how thin the record is here, call the shop before you order so we can confirm what this pipe actually fits and get you the correct side and application.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
Sorry if we got something wrong here. If you think this information isn't correct, .
