Apex Max-Rev Intakes?

Has anyone bought and used these on their '11 on up Apex? Running out of "small" mods to spend money on my '13 XTX!!
Any true performance gains? They're claiming a 600 rpm gain with their package, I already have a Ram-Air lid and PCV from Ulmer, and see around 10800 rpms. Looked at their dyno runs and they made the "most" power with their intakes.
Thanks
Rick

Must not have been a hit!

If I had the newer 11+ apex I would have these. On a couple of my bikes I ran short stacks....
IMO, the newer Apex would benefit for sure, as these engines spend more time at higher rpm than bikes do....
