i'd hang fire and wait to see what fernandez's R3 airboxes are like,the maxi is good and sounds absolutely awesome but "IF" the R3 airbox is better and around the same price you'll be cheesed off,ktec also have something new in the pipeline and i've read a few members on here have tested it with good gains but there not letting on what it looks like yet,got a feeling it will be like the R3 box
