Stock

Was reading an article on exhausts but cannot remember or find article. It was about someone taking out stock exhaust internals on a 2009 adventure and got fruity sound and it did not affect running of bike. It did not say how to do it but it said cheaper than buying an aftermarket exhaust. Any ideas on this.
Thanks
Denis.

I did this on my 1150 GS.
It will be different on your bike but this is what I did.
Unbolt end cap of muffler and slide muffler out of fancy tube.
Cut open one side of muffler to reveal internals.
Gut internals then join ends of pipe inside muffler with a couple of bends and a bit straight pipe.
Some people have not bothered joining the ends.
Weld closed muffler and refit to fancy tube.
