Muffler questions for 2018 Z owners

[custnam]

 Hello. I have a couple questions about the black muffler on the Z. I have the same bike and have noticed that the muffler looks very faded, almost white in some places. Does anyone with the same muffler have this same issue? The 2nd question is probably stupid, but Ill ask anyway. I also just noticed a dent on the bottom of the muffler. I cant think of anyway this got there, other than possibly the muffler hit the spool slider when I hit a big bump. But it seems like the dent and spool are just too far apart for this to have been where it came from. So I thought it might have already been there when I got it. Does anyone else have a dent there? Ive inserted pics for reference. Thanks

The dent is from your spool and riding with either a passenger or too low of a spring pressure. It may have "clearanced" itself enough already, but your going to want to look into it further.

Oh shit, I didn't even think about the spool/muffler issue. Mine's new, so I can't comment on the faded parts. Your muffler seems smoother than mine is though. Mine has a bit of a rough texture/finish.

 I dont ride with passengers, but I did soften the rear suspension. Its definitely the spools. I hit a big pothole today and the dent is worse. Ill tighten up the rear suspension. And remove the spools until I need to use them with my rear stand.

I know this is an older post but yeah that muffler looks almost like it was wet sanded compared to mine.

Just curious, did you clean it when it was hot and the soap dried on it at one point? Did you use anything other than normal wash detergents.
