What You'll Learn
Electric exhaust cutouts can be loud
Electric exhaust cutouts can be very loud. They are designed to give the user control over the sound of their vehicle's exhaust. By opening or closing the cutout valves, the user can switch between a quieter, more subdued exhaust note and a louder, more aggressive one. This is particularly appealing to automotive enthusiasts who want to customise their vehicle's sound.
The loudness of the exhaust is controlled electronically from inside the vehicle. Electric exhaust cutouts are a bolt-on valve that is controlled by a rocker switch in the car. With this type, you can open them a little or all the way, giving you precise control over the volume of the exhaust. The amount of exhaust flow, and therefore sound, can be controlled by the user at any given time.
The predominant reason automotive enthusiasts want cutouts is for the loud, rumbling sound of their engines. However, the sound of the exhaust is not the only reason for installing cutouts. When the cutouts are open, they provide a shorter and less restrictive path for exhaust gases to exit the system, leading to increased horsepower and torque and improving the vehicle's overall performance, especially during high-speed acceleration.
In the context of racing or track use, electric exhaust cutouts are a valuable tool for maximising engine performance. By quickly redirecting exhaust gases, they can help achieve optimal performance levels. However, the impact on performance varies depending on the vehicle's engine and overall exhaust setup.

They may eventually stop working
Electric exhaust cutouts are a fun addition to a car, giving the driver control over the volume of their exhaust. They can be opened a little or a lot, allowing for a precise adjustment of the volume. However, they may eventually stop working.
The electric motor can die, as one user on Reddit reported happening to them. Another user on Trifive.com, who had installed four sets of electric exhaust cutouts over the last decade, reported that one of their butterfly bolts simply fell off while they were driving one day.
The electric cutouts can also fail due to the tough environment in which they are installed. They are attached to the car's exhaust, which can get extremely hot, and they are often placed underneath the car, where they are exposed to the elements. This can cause the cutouts to rust or otherwise degrade over time.
Additionally, the cables that operate the cutouts can get rusty quickly and tend to be a bit finnicky. This can cause the cutouts to become stuck in one position or to not work at all.
It is important to note that the failure of electric exhaust cutouts does not always render them completely useless. In some cases, they may still be operable, but with reduced functionality. For example, they may only be able to be fully opened or closed, without the ability for fine-grained adjustments. In other cases, they may continue to function but with increased leakage.

They can be expensive
Electric exhaust cutouts can be expensive, with prices ranging from $150 to $300 or more for the cutouts alone. The cost of installation should also be considered, as it can vary depending on the vehicle and the complexity of the installation. While it is possible to install them yourself, professional installation is recommended to ensure proper functionality.
The price of electric exhaust cutouts tends to be higher than that of manual cutouts, which can range from $50 to $150 or more. However, electric cutouts offer the convenience of being able to control the volume of the exhaust electronically from inside the vehicle. With manual cutouts, you need to get out of the car and manually adjust the cutout.
The cost of electric exhaust cutouts can also vary depending on the brand and features included. High-end and performance-oriented cutouts can exceed $300, with prices going up considerably based on additional features and brand reputation. It is important to balance your budget with your performance and sound goals when choosing an exhaust cutout system.
While some cheaper options may be available, they may not offer the same quality and durability as more expensive options. It is essential to consider the reviews and input from other users before making a purchase decision. Additionally, some companies may offer extended warranties, which can provide added peace of mind in case of failure.
Overall, while electric exhaust cutouts can be expensive, they offer a range of features and benefits that may justify the cost for automotive enthusiasts seeking sound enhancement and performance boosts.

They can be hard to install
Installing electric exhaust cutouts can be challenging and complex, requiring careful consideration and multiple steps. Firstly, it is important to assess the risks and legal issues associated with installing exhaust cutouts. These aftermarket modifications can create excessive noise and fumes, which may be illegal in certain states or municipalities and pose safety hazards.
The installation process for electric exhaust cutouts typically involves several steps. Firstly, choose an appropriate spot on the exhaust and mark the cut lines. This step requires careful consideration to ensure the cutout is positioned correctly in relation to other components, such as mufflers and resonators, to achieve the desired sound and performance. Then, use an angle grinder or saw to cut the exhaust pipe according to the marked lines.
Next, place the cutout into the created gap and secure it using clamps or welding. This step ensures the cutout is firmly attached to the exhaust system. After that, route the wires from the cutout to the switch inside the cabin. This step involves running wires through the vehicle to connect the cutout to a control switch.
Finally, mount the switch in a convenient location, connect it to a power source, and test the system by turning the switch on and off. It is crucial to ensure that all connections are sealed properly to prevent leaks and that the switch is easily accessible for the driver.
While electric exhaust cutouts offer convenience and quick response, they are not without their challenges. The motors can fail, and the wires must be protected from the exhaust heat to prevent damage. Additionally, proper orientation of the valve is essential to safeguard it from road debris, and securing the mounting bolts with a thread locker is recommended to prevent them from coming loose. Having the cutout professionally installed is recommended if you don’t have the proper tools, and routine cleaning and maintenance are crucial to keeping the cutout in top shape. Additionally, placing an exhaust opening too close to the exhaust valves can have undesirable consequences.

They may not seal effectively when closed
Electric exhaust cutouts are a popular modification for car enthusiasts, allowing them to adjust the volume of their exhaust systems. They work by using a Y-pipe, with one side continuing to the rest of the exhaust system and the other side vented to the atmosphere. This vent can be capped off or left open, allowing drivers to control the sound and flow of their exhaust.
One concern with electric exhaust cutouts is the potential for ineffective sealing when closed. This can happen due to various reasons, and it is a common issue with cheaper cutouts. When closed, these cutouts may not seal properly, resulting in minor leaks that can be noticeable, especially over time as the seals degrade. The leaks can also occur due to improper installation, as some manufacturers may not provide clear instructions, leading to user error.
In addition to leaks, there is also the possibility of mechanical failure. For example, a butterfly valve falling off while driving, as mentioned by one user. Such an incident could result in a significant loss of performance and require immediate attention.
To mitigate these issues, it is generally recommended to invest in higher-quality electric exhaust cutouts, as cheaper options tend to be leakier. Reading reviews and seeking advice from other car enthusiasts with experience can help identify reliable products. Additionally, proper installation and regular maintenance can also reduce the likelihood of encountering sealing issues.
While electric exhaust cutouts offer convenience and sound control, the potential for ineffective sealing when closed is a concern that users should be aware of. Proper research, selection, and maintenance can help minimize these issues and ensure a better overall experience with electric exhaust cutouts.
