Help with finding the right can

you'll need a specific 2007 800R can, previous REV's had a different engine and pipe set up....and the XP won't fit the REV chassis....so you will be limited to getting a specific 2007 model. As far as sound, they are all pretty quiet since the stock pipe has an internal tube than keeps it quiet. I have a Dynoport ceramic can, works fine, didn't notice HP loss (if there was any), but did notice weight drop. From comments on here and what some friends are running, the HPS comes highly reccommended, but i haven't run it myself.....it does look good.

I run the hps can on my 07 800r. No hp loss and just a little bit louder then stock. I would go hps.
