Setup and Installation

Installation of the Vance & Hines Twin Slash 3″ Round Slip Ons requires basic mechanical knowledge and tools. For optimal results and safety, professional installation by a certified motorcycle technician is highly recommended.

Safety Precautions

• Ensure the motorcycle is cool before beginning installation to prevent burns.
• Wear appropriate personal protective equipment, including gloves and eye protection.
• Secure the motorcycle on a stable stand to prevent tipping during installation.

General Installation Steps (Consult a professional or detailed manual for specific instructions)

1. Preparation: Gather all necessary tools and components. Ensure the motorcycle's exhaust system is cool.
2. Removal of Existing Mufflers: Carefully loosen and remove the clamps and mounting bolts securing the stock mufflers. Detach the old mufflers from the header pipes.
3. Installation of New Slip Ons: Slide the Vance & Hines Twin Slash slip-on mufflers onto the header pipes. Ensure a snug fit.
4. Secure Mounting: Attach the new mounting brackets and secure the mufflers using the provided hardware. Do not fully tighten bolts until alignment is confirmed.
5. Alignment and Tightening: Adjust the mufflers for proper alignment and clearance. Once aligned, progressively tighten all clamps and mounting bolts to the manufacturer's specifications.
6. Final Inspection: Double-check all connections for tightness and ensure there are no exhaust leaks. Start the engine briefly to check for proper operation and sound.

Operation

Upon installation, the Vance & Hines Twin Slash 3″ Round Slip Ons will immediately provide a noticeable change in your motorcycle's exhaust note. Expect a deeper, more aggressive sound compared to stock mufflers, enhancing the overall riding experience.

The louvered core baffles are designed to produce a rich, throaty growl while maintaining optimal back pressure for performance. While these slip-ons are designed to improve sound and aesthetics, significant performance gains may require additional engine tuning or a full exhaust system.

Maintenance

Proper maintenance will ensure the longevity and appearance of your Vance & Hines Twin Slash 3″ Round Slip Ons.

Cleaning

• Clean the mufflers regularly with a mild soap and water solution.
• Avoid using abrasive cleaners, harsh chemicals, or steel wool, as these can damage the black finish and heat shields.
• Rinse thoroughly with clean water and dry with a soft cloth to prevent water spots.

Inspection

• Periodically inspect all mounting bolts and clamps for tightness. Vibrations from riding can cause fasteners to loosen over time.
• Check the heat shields for any signs of damage, discoloration, or loose connections.
• Listen for any unusual exhaust leaks or rattling sounds, which may indicate a loose component or damaged baffle.

Troubleshooting

If you encounter issues with your Vance & Hines Twin Slash 3″ Round Slip Ons, consider the following common troubleshooting steps:

• Excessive Noise or Rattling: Check all mounting hardware and clamps for tightness. Ensure the baffles are securely seated within the mufflers.
• Exhaust Leaks: Inspect all connections for proper seating and tightness. A small amount of exhaust paste can be used on slip-fit connections if leaks persist after tightening.
• Discoloration of Heat Shields: While the heat shields are designed to be blue-proof, extreme heat or improper engine tuning can sometimes cause discoloration. Ensure your motorcycle's engine is running optimally.
• Reduced Performance: If you experience a significant drop in performance after installation, verify that the mufflers are correctly installed and not causing excessive back pressure. Consult a professional for engine tuning if necessary.

If problems persist after attempting these troubleshooting steps, it is recommended to contact Vance & Hines customer support or a qualified motorcycle mechanic.
