Stock Exhaust Heat Shields

So, my pipes have a nice coating of surface rust (po had it sitting for quite some time). It cleans up nicely with a wire brush and drill; but, those damn heat shields are welded on! seems pretty cheesy to me.

Anyway, any tips on cleaning the pipes and getting the shields off, then back on?? I'm guessing they'd have to be cut off with a dremel, and then tacked back on with a TIG? Another option would be to take them off, and leave them off? Or, header wrap them?? I wonder how that looks? worse?

I dont mean to be the bearer of bad news... but you may have contaminated most of your exhaust pipes in a way that will encourage a coating of rust to form.

Those exhaust pipes are Stainless-Steel... if you use anything except Stainless-Steel wire-brush or Stainless-Steel-wool to clean them... you will encourage them to rust even faster.

It is simple metallurgy, rubbing NON Stainless-Steel against Stainless-Steel changes the composition of the surface allowing it to combine with oxygen and form "iron-oxide" (rust). Simply touching Stainless-Steel with your hands contaminated with iron-filings can cause rusting. (you will see fingerprints in the Stainless-Steel)

I suggest you consider using a polish SPECIFICALLY marked for cleaning Stainless-Steel. Your pipes should remain pretty nice a lot longer than when using wire-wheel chucked in your drill.

Or just leave them alone. It's just surface oxidation, and if polished up nice they'll just discolor again, especially if the bike is used in the rain and dirt and such.
