I had header wrap on, made pipes all rusty and nasty. I did not remove the pipes, I did remove the right scoop and chin fairing. I used a lil 3" grinding wheel and brown 3M cookie to get the crap off then wet sanded it with 400 grit by hand, then polished it with a polishing wheel on a lil angle grinder and stainless polish. They turn Gold after you ride it. If you go finer than 400 grit it would look even better.
