Strange stains on silencer
« on: June 14, 2020, 06:10:50 PM »
Hi guys,

The previous owner of my 2014 XC hasn't cared much for its appearance, so to speak.
See the strange spots that have developed on the exhaust silencer. Does anyone have an idea how these spots come about? And furthermore, how should I properly try to remove the stains and subsequently maintain the silencer? Any help on that?

Oh and by the way:

Were the spots there when you bought the bike or have they developed since you have owned the bike?

Yes, they were there when I bought the bike. Why do you ask?

Because if they were not there when you bought it my observation definitely wouldn't make sense.

Probably wrong but when I zoomed in as big as I could to me it looked like grey body filler sanded back down ... as if the previous owner had tried to fill dents/scuffs and poorly sanded it back, with no idea of how he would blend the colour in. :027:

I think the outer shell is stainless. The discoloration could be from many sources. Try stainless steel cleaner.

It is stainless steel for sure so as Chico says try to polish it off.

It's the big ugly oem. Replace it with a lighter aftermarket exhaust. You will feel the difference.
