It seems that the standard exhaust is already an akra as we can see here. If yes, don't need to change.

I can send you mine, if you wantIt would be nice if I could put this standard exhaust on my R1200R. I'm sure there will be a lot of them available in second hand.
I won't change them as well...Hi Bonko, I like the stock exhaust too.
Are you going to do them in gold like the forks?I won't change them as well...
Only the colour...
Next winter they'll get ceramic coated... as the whole exhaust system
will that improve looks only, or also longevity? may I ask what they're quoting you to do that?I won't change them as well...

Its called "Patina"just the look.
The reason is, that the exhaust will look ugly after a few month.
The old 2-valve Boxer got blue and stayed blue for year.
The 4-Valve Boxer get blue, then yellow and green... and ugly...
I see it at my GSA every day![]()
