Yes, the single canister FabSpeed reesonates between 2200-2800 RPM. Not bad top down, annoying top up. Typical FabSpeed amazing quality, and it does sound fantastic. It also flows very well, what with the removal of the secondary cats and it being full 2" plumbing.
I am hoping the new system they have will be resonance free, as of right now, the only thing I know of that doesnt' resonate are the systems from Dansk, Gembella, CarGraphic and the PSE.
