The QTP QTEC dual electric exhaust cutout valves include two 3.0-inch outlets and let you switch between routed and bypassed exhaust flow to alter sound and flow characteristics. They are for setups where selectable exhaust routing is desired. The kit ships with wiring, a toggle switch and two 3.0-inch DIY cutout pipes so you can install the valves into an existing exhaust system.
