Is the OEM exhaust cannister clear cotated or in anyway painted?

I washed up and it looks like it could use a bit of metal polish just a bit leery due to the colour making it look coated.

metal polish is your friend.. preferably non-abrasive like Autosol or Flitz..

Last time I used Autosol it was like mild valve grinding compound.
So this is not a coating just a sickly amber gold colour?

Re: Is the OEM exhaust cannister clear cotated or in anyway painted?

Can't speak for the OEM since mine has the Akra but I notice that mine is turnimg a "goldish" color also.

I believe it's from the heat.

Don't know if it can be polished out or not.

However, if the pipe is clearcoated I'd also be afraid that any polishing would also take off said clearcoat.

Re: Is the OEM exhaust cannister clear cotated or in anyway painted?

I have 4-5 different metal cleaning compounds in my arsenal.. the Autosol is about mid-grade when it comes to abrasiveness and usually the first I reach for...That was just a suggestion. Even less abrasive than that is Wenol or Liquid Mirror (sold by Staintune)

No.. that's NOT a coating... the K1300S puts off sun-like heat.. Just discoloration.. No coating.

What I'd do is remove the can.. (takes all of 5 minutes) and start cleaning a spot on the backside...My guess is it'll clean off the coloring without any spiderweb scratches and look like new again...

Re: Is the OEM exhaust cannister clear cotated or in anyway painted?

I hated that single lump of chrome looking stuff on my previous K1300S. I sent the muffler and the mounting strap to Jet Hot Coating where it was ceramic coated to match the frame color. Visually the muffler appeared a bit smaller and the eye was not drawn to it more than the rest of the cycle.

I suspect the discoloration is due to the Chromium or Nickle in the stainless steel. Chrome plated manifolds and exhaust tubes tend to yellow and, where the temp is higher, turn blue as well.

Yep, I have the Akra on my MS edition and it seems to be getting darker the more I run it..Have you tried anything to brighten it a bit?

NO clearcoat can withstand exhaust temperatures! Thus, clearcoating would be a disaster! That's why the exhaust can is made of stainless steel and never coated.

Not yet.

Re: Is the OEM exhaust cannister clear cotated or in anyway painted?

Well, 1 year and two months later I gave the Mother's Mag and Aluminum Polish a go.

Worked perfectly!

Put it on with a dry wash cloth. A little elbow grease and then wiped it off with a clean wash cloth.

I then used a microfiber towel to get off any remaining residue.

Can looks like new!

Be advised, this only removed the bronze/brown tint due to heat discoloration.

Not for scratches in/on the canister itself.
