A lower muffler sits on one side of the exhaust system, taking the spent gases from the header pipe and quieting them before they exit at the rear. On a twin-cylinder Triumph, the exhaust setup typically runs one muffler on each side, so this one is paired with an upper muffler on the other pipe.
Our record on this one is limited to a single catalog listing, so we can't speak to broader fitment beyond the TR6C figure it appears in. Call the shop and we'll confirm fitment before you order.
