What is this strange exhaust rattle and how do I fix it? I believe it has to do with the exhaust butterfly valve, you can see it in the exhaust hole right? Much help would be appreciated.

If you're sure that this rattle isn't caused by a loose baffle within the muffler or a problem with one of the exhaust pipe hangers, it's a simple mater to remove a small spring clip (between the exhaust actuator and exhaust pipe flapper) and hold this flapper in the open position by passing a stiff piece of wire thru the exposed flapper shaft slot and securing it to the exhaust actuator mounting bracket.
