I use Simichrome on my pipes they look awesome!
I have been using it for years on my Harley. It's stuff from Germany made by a company called GFE
just google for a link there are a ton out there.
I usually buy a tube at one of the bike shows for $10.
Wash the pipes first. If you have black crud on them use Wheel Cleaner or I use Dawn Power Dissolver. Works great makes a nice foam and really sticks to get it clean. Then dry thoroughly. Then wrap your finger in a clean soft cotton cloth. a little paste on your finger and apply. Let dry to a haze then use a CLEAN section of your cloth to buff to a bright shine. Then wax them to help keep the crud off.
