Let’s get started and find the perfect rumble for your Softail.
Understanding Your 2006 Softail
Before we dive into muffler sizes, it’s essential to understand your bike. The 2006 Softail model year encompasses several different models, each with slight variations. Knowing your specific model will streamline your search for compatible mufflers.
Identifying Your Softail Model
The 2006 Softail lineup included:
- Softail Standard (FXST): The base model, often a blank canvas for customization.
- Softail Deuce (FXSTD): Known for its stretched-out look and unique rear fender.
- Softail Night Train (FXSTB): Featured a blacked-out aesthetic and often came with a factory-installed performance exhaust.
- Softail Springer (FXSTS): Distinguished by its Springer front end and classic styling.
- Softail Deluxe (FLSTN): A more retro-styled Softail with chrome accents and a comfortable riding position.
How to Identify Your Model:
- Check Your VIN: Your Vehicle Identification Number (VIN) is the most reliable way to identify your model. You can find it on your bike’s frame, title, and registration. Decode the VIN online using a VIN decoder tool. This will provide you with the exact model and specifications.
- Look for Badges: Some models have badges or decals on the tank or fenders that indicate the model name (e.g., “Deuce,” “Night Train”).
- Examine the Features: Pay attention to key features like the front end (Springer vs. standard), rear fender shape, and overall styling. This can help you narrow down the possibilities.
Knowing your specific model is crucial because exhaust systems, including slip-on mufflers, are often designed to fit specific frame and mounting configurations. While many mufflers are designed to fit multiple Softail models, double-checking compatibility is always a good idea.
Key Measurements for Slip-on Mufflers
When shopping for slip-on mufflers, understanding the key measurements is essential for ensuring a proper fit. These measurements typically relate to the diameter of the exhaust pipes where the mufflers connect and the overall length of the mufflers.
Exhaust Pipe Diameter
The most critical measurement is the exhaust pipe diameter. This is the diameter of the pipes exiting the engine where the slip-on mufflers will attach. For most 2006 Softail models, the stock exhaust pipe diameter is typically 1 3/4 inches or 1 7/8 inches, but it’s always best to verify this on your specific model. This measurement needs to align with the inlet diameter of the slip-on mufflers you choose.

- Tools: You’ll need a measuring tool, such as a caliper (preferred for accuracy) or a ruler.
- Access the Pipes: Locate the exhaust pipes where they connect to the mufflers.
- Measure: Carefully measure the outside diameter of the exhaust pipe. Be precise with your measurement. If using a ruler, ensure it is perpendicular to the pipe. If using a caliper, close the jaws around the pipe and read the measurement.
If you’re unsure, consult your bike’s service manual or contact a Harley-Davidson dealership for the exact specifications for your model.
Muffler Inlet Diameter
The muffler inlet diameter is the size of the opening on the muffler that slips onto your exhaust pipe. This diameter needs to match or be slightly larger than your exhaust pipe diameter for a secure fit. If the muffler inlet is too small, it won’t slide onto the pipe. If it’s too large, it may not clamp down securely and could leak exhaust.
Important Note: Some aftermarket exhaust systems, or even the factory exhaust on some models, might have different pipe diameters. If you’ve already modified your exhaust system, double-check the pipe diameter before ordering new mufflers.
Muffler Length and Overall Dimensions
While the inlet diameter is the most critical measurement for fit, the length and overall dimensions of the mufflers also play a role in the bike’s appearance and sound. Consider these factors:
- Length: Longer mufflers generally produce a deeper tone, while shorter mufflers tend to be louder and have a more aggressive sound.
- Shape and Style: Mufflers come in various shapes and styles, such as straight-cut, slash-cut, or tapered. Choose a style that complements your bike’s aesthetics.
- Clearance: Ensure the mufflers won’t interfere with other components, such as the swingarm, rear fender, or saddlebags.
Review the manufacturer’s specifications for the overall dimensions of the mufflers. Many manufacturers provide detailed diagrams with measurements to help you visualize how the mufflers will look on your bike.
Compatibility Considerations
Beyond the measurements, several other factors influence the compatibility of slip-on mufflers with your 2006 Softail.
Stock vs. Aftermarket Exhaust Components
If you’re using stock (original) exhaust components, the compatibility is usually straightforward, as long as the inlet diameter of the slip-on mufflers matches your exhaust pipes. However, if you’ve already upgraded your exhaust system with headers or other aftermarket components, you’ll need to ensure the new mufflers are compatible with those components.
Mounting Hardware and Brackets
Most slip-on mufflers come with the necessary mounting hardware and brackets. However, it’s always a good idea to check the product description to confirm. Some mufflers might reuse existing mounting points, while others may require new brackets. Ensure the included hardware is compatible with your Softail model.
Fuel Management (efi Models)
If your 2006 Softail is equipped with Electronic Fuel Injection (EFI), changing the exhaust can affect the air-fuel ratio. This is because the new mufflers can alter the exhaust flow, which can impact the engine’s performance. While slip-on mufflers typically don’t require fuel management adjustments, it’s something to consider. Many riders will choose to use a fuel management system (like a Power Commander or similar) to ensure optimal performance and prevent potential issues. If you do not change the air filter, the change is usually minimal. (See Also: Will Two Brothers Slip On Exhaust Work For Rebel 300 )
Legal Requirements and Regulations
Be aware of any local noise regulations in your area. Some jurisdictions have strict noise limits for motorcycles. Choose mufflers that meet these requirements to avoid potential fines or legal issues. Look for mufflers with a dB (decibel) rating to get an idea of their sound level. Often, manufacturers will provide this information.
