Replacing a Honda mower muffler with a quieter one

Hi, here is my problem. I'm a musician and an avid grass caterer. I own a HRR2162SDC Honda mower and I find the noise quite annoying. When I mow my grass, I have to wear an over the ear protector coupled with a pair of in-ear hearing protector. Fact is I remember a former brother in law that owned a Honda mower (can't remember which model) that was so quiet, I did not believe it. As far as I can remember, it was a Deluxe model with hydro-static transmission and I think it also had a heavy plastic bridge.

So my question is: would it be possible to replace the present muffler on my mower with a more efficient (understand quieter) one?

Hope I'll find some help on this forum (my hearing and my comfort would be greatly happy if the results are positive).
