How It Works
Install. Control. Drive.
A VLVX valved exhaust is a permanent upgrade with a temporary personality. Here's exactly what happens from install to the first time you open the valves.
Process
How VLVX Works
Three steps from a fixed exhaust note to full control over how your vehicle sounds.
- 01
Install
The valved muffler is integrated into the vehicle's exhaust system.
- 02
Control
Use the supplied electronic control system to command the exhaust valves.
- 03
Drive
Switch between a more refined exhaust character and a louder, more aggressive sound when appropriate.
Exhaust Flow
The Core Concept
One System.
Two Personalities.
A VLVX valved muffler holds two completely different exhaust characters in one piece of hardware. You decide which one your car uses, and when.
Valves Open
Open / Performance
Open the valves when you want a deeper, louder and more aggressive exhaust character.
- Aggressive exhaust note
- Increased exhaust presence
- Sportier driving experience
- Instant sound control
The Complete Guide
How Does a Valved
Exhaust System Work?
A valved exhaust system gives you the ability to control your vehicle's exhaust sound and flow at the push of a button — switching between a quieter, more refined setup and a louder, more aggressive exhaust note.
The Concept
Control Your Sound
A valved exhaust system gives you the ability to control your vehicle's exhaust sound and flow at the push of a button. Instead of having one fixed exhaust sound all the time, an electronically controlled exhaust valve allows you to switch between a quieter, more refined setup and a louder, more aggressive exhaust note.
What Is It?
An Exhaust Valve
An exhaust valve is a mechanical flap installed within the exhaust system. The valve can open or close to change the path that exhaust gases take as they leave the engine. When the valve is closed, exhaust gases are directed through the vehicle's mufflers and sound-reducing components — creating a quieter, more comfortable drive. When the valve is open, exhaust gases can take a less-restricted route through the exhaust system, producing a deeper, louder, and more aggressive exhaust tone.
Valve Closed
Quiet Mode
With the exhaust valve closed, exhaust gases are routed through the muffler system. This helps reduce exhaust volume and creates a more comfortable sound level for everyday driving — a more subtle exhaust note without completely changing the appearance or character of the vehicle.
Quiet mode is ideal for
- Daily driving
- Residential areas
- Highway cruising
- Long-distance trips
- Cold starts when a quieter exhaust is preferred
- Drivers who want a more refined exhaust sound
Valve Open
Performance Sound
When the valve is opened, the exhaust system changes the route available to the exhaust gases. Depending on the system, the gases can bypass some of the muffling components through a dedicated valve-controlled section. This allows more of the engine's natural exhaust sound to reach the tailpipes.
With the valve open, drivers can experience
- A louder exhaust note
- A deeper and more aggressive tone
- Increased exhaust presence under acceleration
- A more performance-oriented driving experience
- Greater control over the vehicle's sound
The exact sound and flow characteristics depend on the vehicle, engine, exhaust configuration, valve placement, and muffler design.
How Is the Valve Controlled?
Electronic Valve Actuation
VLVX Performance valved exhaust systems can use an electronic valve actuator to control the exhaust valve. The actuator moves the valve between its open and closed positions. Depending on the configuration, the system can be controlled through any of the options below — so you can change the character of your exhaust without having to physically modify the system every time you want a different sound.
- Dedicated controller
- Remote
- Switch
- Vehicle-integrated control system
Valve Closed
Refined • Quieter • Comfortable
Daily-driver friendly. A more subtle exhaust note for everyday driving.
Valve Open
Aggressive • Deeper • Louder
Performance-focused. A more aggressive exhaust character when you want it.
One Exhaust. Multiple Driving Experiences.
Instead of choosing between an exhaust that is permanently loud or permanently quiet, a valved system gives you both options. This makes a valved exhaust system an excellent option for drivers who want a more exciting exhaust sound without sacrificing the ability to keep things relatively quiet when necessary.
The Honest Answer
Does a Valved Exhaust Increase Horsepower?
A valved exhaust system is primarily designed to provide sound and exhaust-flow control. Opening the valve can reduce restriction in certain exhaust configurations, but the actual performance gains vary significantly from vehicle to vehicle. A valved exhaust should therefore not be marketed as automatically adding horsepower. Its primary benefit is giving the driver control over the vehicle's exhaust character and sound.
Factors that affect performance
- Engine design
- Exhaust diameter
- Catalytic converters
- Mufflers
- Valve location
- ECU tuning
