while going through the bike decided to remove the exhaust and give it a polish. It had turned a brownish bronze color in lots of places along with purple patches in spots.
Did some reading, major choices seem to be using either mothers or blue magic. Tried mothers but saw no real difference, then tried Blue magic and used a Meguirs 8 inch orbital buffer then mothers as a polishing coat. Did a good job, took about 90 mins for all the pieces.
