are you talking about the velocity stacks? if so then no they aren't all 4 the same length, 2 long ones and 2 short ones. I think the short ones are on the outside, but aren't 100% sure as it was 3 months ago that I had the airbox open
I mount my 2014 bell mouth tomorrow, i ll post a pic. they are the same as the old model but slash cut like the old HRC model.
The production 2012 bell mouth have the same size as old blade since 2008, exactly the same but slash cut like these HRC.
I questioned Honda about the SP's stacks but they did not know much about them, they have fascinated me no end hence why I took some pictures, I could not remember if the last 2013 I did have oval stacks in this configuration.
can you order them from honda ? i have asked 2 dealers in germany, both were not alble ( or willing ) to order 17215-mgp-a90 maybe EU,UK bikes have an other part number
