I currently have stainless hi output duals.. After getting the bike back from dyno tuning. My pipes and heat-shields are very discolored.

Is there a good way to clean these without ruining finish?

 

I used green scotch brite on my 2-1 stainless hi-output. Just go with the brushed finish that is already present. I tried some chemical cleaners but they didn't seem to work as well.

And try a spot first that is not as noticeable so you know what your results are going to be.

 

Ok thanks. I wasn't sure If there was a protective layer that was going to get ruined

 

I've been using Nevr Dull for years for all my chrome, stainless, and other metal parts and exhaust (http://www.nevrdull.com/).

This stuff is fantastic and doest ruin or scratch the finish at all.

 

Hoosier Metal Polish best stuff I ever used and really easy to use.

 

That's the beauty of brushed stainless...you can't hurt it!
