Will a slip on for a 09 zx6r fit on a 04 636? And will any other years work as well?

 

hmm, I never thought about that option. Measure the outlet and the hanger distance along with the mounting height. A stock can? If it was an aftermarket can, then of course you could ask them for this info.

Welcome to KF and good luck on your search

 

It is an aftermarket can but it connects to my right foot peg, not to the hanger. And when asked them they said they were unsure if it would fit, so I came here.

 

Generally, the hanger is the passenger peg mount. What aftermarket slip on are you looking at?
