Has anyone installed the Fiamm Freeway Blaster on your Vulcan 900? It has 8 in. x 4 x 5 dimensions and it seems much larger than stock. The Nautilus Stebel is even larger but I went w the Fiamm after some research. Of course, I already ordered it (yesterday fr Amazon) in my zeal to mod. I still have time, possibly, to change it as they haven't shipped yet. Was this a stupid decision, fitment-wise? Thanks.
