I am running the B320 also which seems to be very similar to the powerboost. I can tell you with having the E6/E7 quick mounts on the front the clearance is tight. To the point where if you tried to remove it while hot you'd get burned.
Before that I used the Evo 55 pipe and the standard thumb screws and it was still a cautious attempt to ensure I didn't burn my finger.
Some people run the Powerboost and I don't think there's fitment issues, it just might be tight but not enough to burn the canopy.
