I want to play with the exhaust on my bike, remove baffles, or other mods. But I don't want to mess up my stock exhaust. I guess I want to experiment to find the right mod for me. My bike is a 2012 c50t. I have found several other stock exhaust systems, but don't know what years will fit my bike. I have seen a 2006, 2009 and 2010 available.
