Help with pipe...please!

[Taminator]

Picked up an hmf pipe from a friend. It was off a 500 Outty, should it fit my 650 outty??? He thought it should.
After searching here and other sites I've found mixed information and nothing really answers it. Parts # is the same on some sites, dif on others.
Gonna call a dealer tomorrow, but if someone here knows...

It is the same pipe but they switched from the spring fastened to the clamp style in 08 I think. If its from the same year bike as yours it should work
