If I recall correctly, the first two digits of the serial number are the year of manufacture. Unfortunately, I don;t recall when they first started using the Catalytic mufflers.
My Jonsered 2152 is a 2005 and had the Catalytic muffler. If I recall, it was advertised as the "e-tech" model (which meant it complied with the EPA regs - part of which meant a Cat muffler). It also had a green fuel cap, which I believe was also an indicator of the catalytic muffler. It's been a long time, but I believe the muffler may also have had "CAT" or "CATALYTIC" stamped on it somewhere.
One source of a non-catalytic muffler for these saws is Bailey's. They sell an
OEM, Non-Cat muffler . It was originally intended for their older non-cat models, but fits the Husky 353 or Jonsered 2152 which came with catalytic mufflers. NOTE: I just found this on a search of th eBailey's site. I suggest verifying the fit with Baileys based on the serial number of your saw before ordering. Their customer service includes some pretty knowledgeable chainsaw folks (or at least it did back when I ordered mine).
There are cheaper, non-OEM mufflers out there (Baileys used to sell one. Maybe they still do.) There may also be cheaper sources for the OEM version. Some of the aftermarket stuff is good, some is pure junk (and no, I've not kept track of who makes "the good stuff") If you are shopping for a muffler from other sources, a muffler described as an "EPA muffler" is most likely catalytic.
If you are replacing the muffler, I'd also recommend having the muffler gasket on hand, particularly for an older saw. If I recall, there is also a muffler bracket on these saws. If so, take a look and make sure it's in usable condition. My saw was relatively new, so if it did have one, I did not replace a bracket.
Do remember to retune your carb after changing the muffler. The reduction in backpressure changes how the fuel-air mixture is pulled into the engine.
