The QTP QTEC single electric exhaust cutout valve is built for systems using a 3.0-inch outlet with a 2.75-inch DIY pipe supplied. It lets you open or close an exhaust bypass to change sound and flow characteristics without permanent piping changes. The kit includes wiring, a toggle switch and the provided cutout pipe for a user-installed, adjustable exhaust path.
