darby_07 darby_07 and I spent a rainy couple of days cutting off the bottom and hollowing the stock exhaust from his CB650R. We figured if we completely screw it up it'd be no big deal as he has an akropoivc and I would just leave mine alone. The operation was a success, though, and I took off my exhaust and put on the one we modified.

Picture time:


I started off small, because we weren't sure of the internal layout, and I did not want to damage the catalytic converter.

Found the cat, so now we are good to go hacking out the baffling.

This is the only picture we took anywhere near fully hollowed. We cleaned it up a bit more before reassembly.

I’m very interested to see a side by side video between that and the Akra. It may be something to tinker with over the winter.
