Leak
It probably only happens when you let off the gas, right? Air is getting sucked into the exhaust (you have a small leak) and that's the problem. I have 2010 Brute with the same thing happening. No matter how I move the clamp and tighten it, I can't get it to seal. My next step is to buy some hight temp gasket material and try to spread a little bit of it at the joint between the pipe for the front cylinder and the muffler.
Use a bottle of soapy water and spray the exhaust while the machine is running. You will see bubbles coming from the spot that it is leaking.
