I'm mostly a lurker as my CM400 is a riding project. I'll post up a thread in the project thread soon. Anyways, I installed a MAC 2-1 Megaphone exhaust since the stocker was beyond hope. After installing the exhaust it's quite raspy. Not bad...but not good. I mean I've been riding it like this for pretty much the whole summer but would like to try something different. I thought maybe pull out the baffle and see if it's tolerable at all. Ummm NO. lol. WOwzers! I think the dead are still banging on their caskets tell me to shut it. I noticed that it's just empty and there's no glass packing. If I wrap the baffle with some glass with it tone it down a bit? It's like there's a pack of pissed off bees in my muffler.
