If it is? My exhaust pipes are completely covered in medium brown rust!!! The resonator and muffler are nice clean silver.

I know that there are different grades of stainless, but is there an over abundance of iron in these particular pipes to cause them to rust?

Hey Bob,

I "magnet" tested the stock system and only the muffler and resonator were stainless. The pipes are not. Seems your "rust" test method yielded the same conclusion. :-)
