Our factory complete electric exhaust cutout kits give you the best of both worlds--an OEM-quality quiet sound for the street, and a wide-open race growl for the track. These kits are designed to be welded or clamped into the existing exhaust, and can be opened and closed from inside the cockpit with an included "one-touch" flip switch. Even better, one rocker switch controls both sides of the dual cutouts, or they can be wired independently of each other. You control the volume and the flow. Exhaust cutouts fit any car or truck, from old-school musclecars to high-tech imports. Features: 1. Lightweight CNC Machined Anodized T-6061 Aircraft Aluminum Alloy 2.
