How To Tell If Mustang Has Active Exhaust
Determining whether a Ford Mustang is equipped with active exhaust involves a combination of visual inspection, interior controls examination, and potentially, verification through vehicle documentation. Active exhaust systems allow drivers to modify the sound characteristics of their vehicle's exhaust note, typically offering modes ranging from quiet operation to a more aggressive and louder output.
Visual Inspection
The first step in identifying an active exhaust system is a visual inspection of the exhaust components located beneath the vehicle. This inspection aims to identify the presence of exhaust valves, which are a key component of an active exhaust system.
Locating the Exhaust Valves
Examine the exhaust pipes, particularly near the mufflers or resonators. Look for small, cylindrical devices attached to the exhaust pipes. These are the exhaust valves. They are usually electronically controlled and connected to a small motor or actuator.
Must Read
An exhaust valve is a butterfly valve mechanism integrated into the exhaust system. It opens and closes to redirect exhaust gases, altering the sound produced. When closed, the gases are routed through a more restrictive path, often a muffler, resulting in a quieter sound. When open, the gases bypass this restrictive path, leading to a louder and more aggressive exhaust note.
These valves may be slightly difficult to spot due to their placement and the overall complexity of the exhaust system. Using a flashlight can greatly assist in locating them. Also, consider the model year of the Mustang, as active exhaust became more prevalent in later models.
Interior Controls Examination
The next crucial step is to examine the interior controls and settings of the Mustang. Active exhaust systems are typically controlled through the vehicle's infotainment system or via dedicated buttons or switches.
Navigating the Infotainment System
Modern Mustangs equipped with active exhaust often integrate the controls within the infotainment system. Look for a menu option related to "Drive Modes" or "Exhaust Mode."
Access the vehicle's settings through the infotainment screen and search for these options. If an active exhaust system is present, you should find settings that allow you to select different exhaust modes, such as:
- Quiet Mode: Designed for minimal noise, suitable for residential areas or early morning starts.
- Normal Mode: A balanced setting suitable for everyday driving.
- Sport Mode: A more aggressive exhaust note, enhancing the driving experience.
- Track Mode: The loudest setting, intended for track use and maximum performance sound.
The presence of these selectable modes strongly indicates the presence of an active exhaust system.
Checking for Dedicated Buttons or Switches
Some Mustang models might have dedicated buttons or switches on the center console or steering wheel to control the exhaust mode. Look for buttons labeled "Exhaust," "Sound," or similar terms. Pressing these buttons should cycle through the available exhaust modes, and you might hear a noticeable change in the exhaust sound as you do so.
If you find such buttons and observe a change in the exhaust note, it is highly probable that the Mustang has an active exhaust system.
Auditory Verification
Once you've identified potential controls, verify the system's functionality by listening to the exhaust note as you change modes. This requires starting the vehicle and listening carefully as you cycle through the different settings.
Listening for Exhaust Note Variations
Start the engine and allow it to idle. Cycle through the available exhaust modes using the infotainment system or dedicated buttons. Listen closely for changes in the exhaust sound. A distinct difference in volume and tone between modes confirms the active exhaust system is working.
For example, switching from "Quiet" to "Track" mode should produce a noticeable increase in the exhaust volume and a deeper, more aggressive tone.
Vehicle Documentation Review
If visual inspection and interior controls examination do not provide conclusive evidence, consulting the vehicle's documentation can be helpful. This includes the owner's manual and the vehicle's window sticker (if available).
Owner's Manual
The owner's manual often contains detailed information about the vehicle's features and options. Search for sections related to the exhaust system, drive modes, or vehicle settings. If the Mustang has active exhaust, it will likely be mentioned in the manual, along with instructions on how to operate it.
Window Sticker
The window sticker, also known as the Monroney sticker, lists all the standard and optional equipment on the vehicle. If the Mustang was originally equipped with active exhaust, it should be listed as an option on the window sticker. This is a definitive way to confirm whether the vehicle was built with this feature.
Aftermarket Systems
It's important to note that active exhaust systems can also be installed aftermarket. If the visual inspection or documentation suggests the Mustang did not originally have active exhaust, but you observe exhaust valves and interior controls, it's possible that a previous owner installed an aftermarket system.
Identifying Aftermarket Systems
Aftermarket systems often have different control interfaces compared to factory-installed systems. They might use a separate remote control, a smartphone app, or a dedicated switch that is not integrated into the vehicle's infotainment system. The quality of the installation and the brand of the components can also provide clues about whether it's an aftermarket system.
Look for branding on the exhaust components or control interfaces that are not associated with Ford. If you are unsure, consulting with a qualified mechanic or exhaust specialist can help determine whether the system is factory-installed or aftermarket.
Summary
In summary, identifying whether a Mustang has active exhaust involves these steps:
- Visual Inspection: Look for exhaust valves on the exhaust pipes.
- Interior Controls Examination: Check the infotainment system and for dedicated buttons for exhaust mode selection.
- Auditory Verification: Listen for changes in the exhaust note as you switch between modes.
- Vehicle Documentation Review: Consult the owner's manual and window sticker for confirmation.
- Consider Aftermarket Systems: Be aware that active exhaust can be installed aftermarket.
By following these steps, you can accurately determine whether a Ford Mustang is equipped with active exhaust and understand how to operate it.
Practical Advice
Understanding your vehicle's features is crucial for optimal driving experience and maintenance. Here are some practical insights:
- Regularly inspect the exhaust system for any signs of damage or corrosion, especially around the exhaust valves. This ensures the active exhaust system functions correctly.
- Familiarize yourself with the controls of the active exhaust system to utilize it effectively in different driving situations.
- If purchasing a used Mustang, always verify the presence and functionality of the active exhaust system before finalizing the purchase.
- Consult a professional mechanic if you suspect any issues with the active exhaust system. Attempting repairs without proper knowledge can lead to further damage.
