Default Exhaust tip discoloration

The warranty on my FLRT expires in less than a month. The trike runs well but I am curious as to why the left exhaust outlet discolors. The dealership that performed its first major service said nothing about this concern. When I pointed it out to the service manager, I was told this was normal. I have nothing in writing that I reported this while under warranty. Should I be concerned?

On a stock 2-1-2 the left tip is always darker. It doesn't have the same flow as the right side thus exhaust builds up on it.

It is sort of a brown color but it comes off black when rubbed with my finger. The right side has almost no residue.

If it rubs off, its from the exhaust gases, blue coloured from heat won't rub off. Its likely from too rich a mixture or oil usage. For whatever reason that side is flowing more exhaust.

Its a normal condition.Most people who are concerned with this just wipe off the residue from the exhaust gases.Chopper Man had the right answer for this condition.
