I have the 4 by 4 exhausts,
regular riding keeps the inside dry and clear,
but the chrome is going,
I usually remove them annually,clean and polish all over with Autosol,using a nylon toothbrush to clean/polish the nooks and crannies,
but in both inner pipes I am getting rust near the mounting brackets,
so,I need advice how to stop it going further,
and maybe preventing completely !!
your help is needed !!
