Very good point. A simple visit and discussion with the Service Manager or better yet one of the mechanics might answer all these questions for the OP.
I bought and installed one on my 900 couple years ago. Can't remember what it cost me. I think I did a thread here. Might search for it.
I love mine. One of the better, if not the best mod I've done.
Dennis, calm down. I simply asked to clarify the professionalism of the employee based on money paid. That's how Capitalism works. No negativism pointed at anybody. You started the conversation.
