Mechanically baffled exhausts (No Packing)

Hi everyone,
So since I’ve upgraded to a 650, I now have many more options when it comes to exhausts compared to my old Outlander 330.
The thing is, I don’t really want to have any packing to have to change or worry about, which is why I really like the idea of a fully baffled or mechanically baffled exhaust, whatever you would like to call them.
I’m having trouble trying to find these "packingless" exhausts, I’ve heard of MBRP selling a muffler with no packing, but have had no luck finding a video or sound clip of one. Does anyone know of any other exhausts that don’t use packing in the muffler? Sound clips would be cool too! :thumbsmilie:

I know there’s already umpteen-million threads on exhausts, but couldn’t find any that focused on mechanically baffled exhausts. Sorry if there’s already a topic on this!
