jrns, I'm a big fan of the Moriwaki. I didn't really see any other exhausts that caught my eye except for the super pricey ones like the Wyverns. The only other reasonably price exhaust that I had considered was the SP Tadao Megaphone. The tone is pretty deep as you can tell by the video; I like that it does not make the bike sound like an inline four sportbike. I honestly can't even hear them when I'm riding above 20MPH as the wind noise drowns it out.
Josiah, I had mine aluminum-ceramic coated locally by a place called M&R Coating for $175. If you can't find anything local, there is also a company called Jet Hot that can coat your header if you mail it in to them. They quoted me $215 and you pay shipping costs both ways.
