Went to Meineke today, got the cutout and u-bend delete put in, and deleted the resonator. Took some video comparing with it closed, and with it open, though the video doesnt do justice to how it sounds with it opened...Nice low rumble at lower RPMs, but it screams in the upper RPMs.

kinda sounds like James's firebird, only less buzzy
