2. Setup & Installation

Proper installation of the Super Q Quiet Baffle is crucial for optimal performance and safety. If you are unsure about any step, it is recommended to consult a professional motorcycle mechanic.

2.1 Safety Precautions

• Ensure the motorcycle exhaust system is completely cool before beginning installation to prevent burns.
• Wear appropriate personal protective equipment, including gloves and eye protection.
• Work in a well-ventilated area.
• Refer to your motorcycle's service manual for specific instructions regarding exhaust system removal or modification.

2.2 Required Tools

• Basic hand tools (e.g., wrenches, screwdrivers) suitable for your exhaust system.
• Possibly a drill if new mounting holes are required (unlikely for a baffle replacement).

2.3 Installation Steps

1. Prepare the Exhaust: With the exhaust system cool, locate the existing baffle (if any) or the opening where the baffle will be inserted.
2. Remove Existing Baffle (if applicable): If your exhaust system has a removable baffle, carefully remove the retaining screw or clip and extract the old baffle. This may require some force or a penetrating lubricant if it's seized.
3. Insert Super Q Quiet Baffle: Slide the Vance & Hines Super Q Quiet Baffle 21912 into the exhaust pipe opening. Ensure it is fully seated and aligned correctly.
4. Secure the Baffle: Use the provided hardware (or existing hardware if compatible) to secure the baffle in place. Typically, this involves a screw that passes through the exhaust pipe and into the baffle. Tighten securely but do not overtighten.
5. Repeat for Second Baffle: If installing a pair, repeat the process for the second exhaust pipe.
6. Final Check: Verify that both baffles are securely installed and that there are no loose components.

3. Operation

After installing the Vance & Hines Super Q Quiet Baffle 21912, you should immediately notice a reduction in the overall exhaust sound level. The baffle is engineered to provide a quieter ride while maintaining the characteristic deep tone associated with Vance & Hines exhaust systems.

The exact level of sound reduction can vary depending on the specific Vance & Hines exhaust system it is installed in, as well as the motorcycle model. Allow for a short break-in period, during which the sound characteristics may slightly settle.

4. Maintenance

The Vance & Hines Super Q Quiet Baffle 21912 is designed for durability and requires minimal maintenance.

• Periodic Inspection: Regularly check the baffle's retaining screw and ensure it remains securely fastened. Vibrations from motorcycle operation can sometimes loosen fasteners over time.
• Cleaning: If carbon buildup occurs on the baffle, it can be cleaned using appropriate exhaust cleaning products. Ensure the exhaust is cool before cleaning.
• Damage Check: Inspect the baffle for any signs of damage or wear. If the baffle is damaged, it may affect its performance and should be replaced.

5. Troubleshooting

If you encounter issues after installing your Super Q Quiet Baffle, consider the following:

5.1 Unexpected Sound Level

• Issue: The exhaust sound is not significantly reduced, or it sounds different than expected.
• Solution:
  • Verify that the baffle is fully seated and securely fastened within the exhaust pipe. A loose baffle can vibrate and produce unwanted noise or fail to reduce sound effectively.
  • Ensure that the baffle is compatible with your specific Vance & Hines exhaust system. Refer to the compatibility list in Section 1.
  • Check for any exhaust leaks around the pipe connections, as these can affect sound.

5.2 Baffle is Loose or Rattling

• Issue: The baffle is rattling or feels loose inside the exhaust pipe.
• Solution:
  • Allow the exhaust to cool completely.
  • Inspect the retaining screw or hardware. Tighten it if it's loose.
  • If the screw is stripped or damaged, replace it with appropriate hardware.
  • Ensure the baffle is correctly positioned and not obstructed.
