Okay so I got one of these new catalytic mufflers with my new 68.5cc Slant Head kit. Now after logging about 450 miles on it with a 32 tooth sprocket I would really like to know what exactly is going on in these mufflers? Has anyone dissected one yet? They are not cleanable! I have noted that it has a heat shield on it so it must be getting hotter than previous mufflers. Is it going to clog up or is it getting hot enough inside to self clean? Should I spring for an older cleanable design or something else like a tuner pipe or just keep pluggin' along on the one I have?
