What does the number on the exhaust mean. Most that I have seen say HM404, but some are different. Is it pertaining to the quality of the metal or something?

Should just be a basic stock model number pertaining to a certain year. Do not think quality would have anything to do with it.

I've seen the 404 stamp on different models and years, but maybe that's it.
