So i recently bought a 2009 vulcan 900 custom and i like the looks of the stock exhaust but it is to quiet and im wondering if it is worth debaffling the exhaust stage 1 2 or 3 and if i do what do i need to do as far as air/ fuel or do i need to do anything since it is fuel injected

I felt the same, IMH, it's too quiet. I removed the end plate, drilled 4 - 1/2" holes and reinstalled the end plate. Now has a slight rumble with the stock appearance. You can do exhaust or intake but not both without affecting mixture.

BTW, post an introduction or you may get locked out of the forum until you do.
