Is there a noticeable difference in performance or are all essentially the same? Comments on each? I need an air cleaner and like both styles... not sure which way to go.

 

I added a Heavy breather last season and love it. Although I cant attribute any performance gain to just the heavy breather, after adding VH pipes and the Heavy breather I noticed a difference. I can say, however, I really prefer the look of the HB.

 

I'm interested in hearing what folks have to say on this one too. Thinking about doing something to my fatbob to help make the brake pedal a little more accessible.

Not sure if i'd go with a PC or just have the dealer remap.

 

Both should deliver the on demand air flow that the motor requires at any speed. Provided you arent running a 150" bruiser ( do they even make a 150?). I put mine on for leg clearance, also relocated the horn, big differrance. But I think numbers wise the heavy breather should come out ahead.

 

I bought the HB cuz it was the best looking AC out there IMO. Performance advantage over other air cleaners should be negligable.
