Does anyone have any experience in making an aftermarket exhaust a little more bearable? I've got the Yoshimura exhaust on my 330 Ace and it's just too obnoxious for me. It's been loud from the start, so the packing should be good. I haven't had it out on the trails yet, but just around my property, I'm worried about annoying neighbors. I contacted Yoshimura by email and they actually quickly replied that they don't make a quite insert for this muffler. I was impressed by the quick reply. So is there a small clamp on unit I could put on after the muffler? Any other tricks? Maybe I could make my own quiet insert?
