Its for vibration. It adds mass and may dampen some harmonics.

Theres probably a band in the rpm range where the exhaust may "sing" or vibrate. This "tuned mass" probably counters it.

Interesting how it's only on the left side...

It maybe only be needed on the left. I assume the left vs right arent identical pipes, different routing, bends, mounting points etc change the vibration response characteristics of the pipe. So from a dynamics pespective the two sides are different animals.
