EVIL ENERGY Dual Electric Exhaust Cutout Valve Remote Switch (2.0/2.25/2.5/3 Inch )

This electric exhaust cut out is specifically designed for single exhaust pipe to enhance the vehicle performance and deliver an aggressive deep sound. Professional installation is highly recommended.

How the Electric Exhaust Cutout Works

The electric exhaust cutout lets you change the exhaust flow using the remote control. Press CLOSE to close the cutout valve and direct the exhaust gases through the muffler for a quieter, more controlled exhaust sound. Press OPEN to open the valve and allow the exhaust gases to exit through the cutout, bypassing the muffler for a louder and more aggressive sound.

A small amount of clearance around the butterfly valve helps prevent the valve from binding as the exhaust system heats up. Because of this clearance, a slight amount of exhaust leakage may occur when the valve is closed. Minor leakage is generally normal and does not necessarily mean that the valve is faulty.

If the leakage is excessive, the valve rattles, or the exhaust sound changes unexpectedly while the valve is closed, check the valve position, mounting hardware, and exhaust connections.

How to Choose the Best Exhaust Cutout Installation Location

The installation location affects both the sound level and tone of the exhaust. The cutout should be installed downstream of the catalytic converter, with enough space for the valve, motor, wiring, and exhaust outlet.

• Location 1 — Before the center muffler: This position bypasses more of the exhaust system when the valve is open, producing a louder and more direct exhaust sound.
• Location 2 — Between the center and rear mufflers: This position allows the exhaust gases to pass through the center muffler before exiting through the cutout. The result is usually a deeper and more controlled sound, making it a popular choice for street vehicles.

Before installation, confirm that the selected cutout size matches the vehicle’s exhaust pipe diameter. Make sure the valve and motor have enough clearance from the ground, suspension, body panels, and other moving parts. Route the wiring away from excessive heat, sharp edges, road debris, and areas where water may collect.

For a dual-exhaust system, install the two cutouts in similar positions on the left and right exhaust pipes whenever the vehicle layout allows. This helps maintain more consistent exhaust flow and sound on both sides. Professional installation is recommended.

An open exhaust cutout can be very loud. Please check local noise and emissions regulations before using it on public roads.

How to Troubleshoot the Electric Exhaust Cutout System

If the exhaust valves do not open or close properly, it does not always mean that the motor has failed. Park the vehicle in a safe, level area, turn off the engine, and allow the exhaust system to cool completely. Then follow the steps below to identify whether the problem may be related to the power supply, control box, motor, or valve.

Step 1: Check the Control Box and Power Supply

Make sure all wiring connectors are securely connected and that the system is receiving a stable 12V power supply. Press the OPEN and CLOSE buttons on the remote control and listen near the black control box. A brief clicking sound usually indicates that the control box is receiving the command.

• If there is no clicking sound, check the fuse, power connection, wiring, and remote control first.
• If both valves stop working at the same time, begin by checking the power supply, remote control, and control box.

If the power supply and connections are normal but the control box remains silent, the control box may be faulty.

Step 2: Check the Motor and Valve

If the control box clicks but a valve does not move normally, check the wiring connector on that motor. Use the remote control to fully open and close the valve. A properly working valve flap should move smoothly and reach both the fully open and fully closed positions.

• If only one valve is affected, inspect that valve’s wiring, connector, motor, and flap.
• If the flap does not respond, moves unpredictably, or stops before completing its travel, there may be a loose connection or mechanical binding.
• If the motor makes a repeated clicking or rattling sound when it starts to open, the motor or internal gear mechanism may be damaged.

If the valve appears to be stuck, do not operate the remote repeatedly. Repeated operation may place additional strain on the motor and its internal gears.

When Should the Control Box or Motor Be Replaced?

If the 12V power supply, fuse, wiring, and remote control are working properly but the control box does not click or respond, the control box may need to be replaced.

If the control box responds, the motor connection is secure, and the valve flap is not blocked, but the motor still rattles or cannot complete a full open-and-close cycle, the affected motor may need to be replaced.

If you are unsure which part is causing the problem, please contact us at support@ievilenergy.com. Include a short video of the issue, your product size, order information, whether the control box clicks, and whether one or both valves are affected. This information will help us identify the correct replacement part more quickly.
