Cleaning long tubes...

[TheTeacher]

I just bought a pair of used BBK ceramic long tubes with about 9k miles on them.

Is it good/worth it to clean the insides? If yes, how?

Also what would you clean the outside with?

Thanks in advance

HOPEFULLY someone took care of the headers since they are ceramic coated. Mine stay looking brand new mile after mile. I just wipe them off with a little polish between cruises. As for the inside, I wouldn't worry about it.

With my intake off I can actually see mine down there. They look pretty good with six months of hard driving on them. Never heard of cleaning the inside.
