Good stainless pipe restorer?

[macx]

Pipes on my 2011 R1200RT are discolored.

 

What's a good restorer and where to get it?

 

Thanks!

I got a lot of the discoloration removed and the rest shinned up pretty good with some cheap buffing wheels from Harbor Freight and some paste metal polish using my cordless drill.

My pipes were far from shinny when I started.
