WHOA!!! the muffler is stainless? Just my opinion, but you've somehow managed to pull off a really clean and classy look on your bike. With all of that black and those beautiful pin stripes, it looks simple yet expensive. I'd suggest stripping the paint off of the muffler with a chemical stripper and seeing how it looks on the bike.
Ceramic coating would look great too. and the aluminum won't be affected.
