Says it right on the F.I. product page:
•The X Pipe has 3 options. Non Resonated, 12" Resonators or 18" Resonators. The resonators are strictly noise canceling devices. They DO NOT hinder performance at all. They are primarily designed to cut down interior noise resonance AKA "Drone"! The longer the resonator, the quieter the interior noise.
