One other thing, please help me with! I have 2006 Spirit 750.
I have found two stock exhausts for sale locally, one is from 2004 Aero 750, the other from 2009 Aero 750.
I've read somewhere than head angles are different and that Aero and Ace are interchangeable, but not Shadow, can anyone confirm this?
I'm tired of the hole saw mod I did to my bike, it's too loud and want to go back to stock quieter sound.
