Yep, that's my bike, I was amazed how "easily" they fit in there, no trimming required, just lots of little adjustments to get it right. As you can see in the pic, I have my compressor for my front air ride on the throttle side of the fairing, so I couldn't use the hogtunes bracket. This was cheaper anyway

 

Will a 300 fit on the hog tunes bracket?

 

i believe there are pictures around here somewhere of one mounted up on the hogtunes bracket.

 

The big problem with the SS PN4.520D is the loss of your FM signal. There is a few threads about it. A few seem to have the problem, and a few don't. $100 vs $400, how important is FM too you?

I'm very curious as to what the actual ratio because it seems like you'd hear more from the people who loss their FM as opposed to the ones who didn't. The saying goes "if you're happy with something you'll tell 1 person, but if you're not happy then you'll tell 10".
