The Streetfire crew ran across this exhaust system cutout gizmo from Bayshore New York's own Kooks Custom Headers at the 2006 PRI show. While an exhaust cutout is certainly not a new idea, this one is using technology reverse-engineered in part from Corvette Z06 innards. The exhaust cutout works either with slight touch of hand from within the vehicle, or by direct signal input from the throttle position sensor. Everyday driving results in quiet stealth mode. Lead foot action? Hey-yo! Wide open throttle triggered exhaust uncorking is amusement we can all use. The rest of the video unfolds into work safe header and exhaust system porn.
