intake pipe

Need advice on my intake pipes I have three that have rust on the inside of the tubing in the area close to exhaust pipes there is not a bit on the outside of the pipes.Not sure what type of coating was on them from the factory as it is the standard silver coating so the guestion is how to remove the rust on the inside as some is beyond the bends and how to replate the inside to stop from rusting in the future and were to send for plating?
Thanks in advance.

Most 320's and 360's are cheaper to replace than to replate. I don't believe there is any reasonable way of plating the inside.
ECI and Superior pipes are around 40 bucks apiece for the most common pipes. Many of the IO pipes are much more expensive.

Thanks for the info I have an angle valve eng and the pipes are a lot of money need to save these if possible any idea on chemical cleaning out rust and plating or some other way to stop the rust is best for me.
Thanks Bob
