Here's a brief how to tutorial installation video of me removing the stock exhaust (muffler) off of the kawasaki ninja 300 and installing an aftermarket slipon exhaust system in this case it was a leo vince gp corsa which I purchased second hand from a fellow ninja 300 forum member

So I put a Yoshi exhaust (full system) in my 300. Now I have the stock exhaust lying around. I want to sell it on CraigsList but have no idea how much to ask for it. Any thoughts?
