QTP 4in Weld-On QTEC 3 Bolt Flange

This kit allows you to switch from a stealth quiet exhaust to a wide-open, high-horsepower setup with the flip of a switch. You can adjust back pressure to potentially save gas and experience performance gains, even with an existing aftermarket exhaust system.

Constructed with a CNC 6061 aircraft aluminum body, stainless steel butterfly plate, and shaft, this cutout features a high-torque DC gear drive motor for strong operation. It includes a weatherproof wiring harness, locking weather-tight connectors, and a 2-position momentary toggle switch for adjustable control from closed to fully open. The kit is proudly made in the USA and includes the electric valve, wire harness, switch, a 4.00-inch stainless steel Y-pipe, instructions, and hardware.
