Has anyone tried to polish the inside of the muffler tips? It's bugging me that only about the 1st half inch is smooth and shiny, the rest of the chambers the aluminum is rough surface and stays dirty as crap.
Curious what, if any steps could smooth and polish out the tubes a few inches in so it's not always discolored.
I've tried some aluminum polish but that does nothing it's so rough. Assume some 400 grit sandpaper and then polish or is there a better idea?
