different colored residue on my exhaust today

[oldschoolsdime92]

I rode about 135 miles today and noticed my exhaust had a brown residue on it instead of the normal black. Any thoughts?

Raped by the monkey after his frog died?

The exhaust color on my Sprint has always been a light brown / tan. It's much more noticeable since I switched out the stock exhaust with the D&D. Both sets of pipes had the expected black carbon in the pipes with the tips being the brown color. Did you change your tune at all before the trip?

well, when I wipe it off its black, its just brown on the tip. I haven't messed with the tune in almost 7000 miles. Maybe its always been this way and I've never noticed it.

if your tip is brown you're doing it wrong

I filled up at shell, I don't normally run shell.
