4. Package Contents

Verify that all components are present and undamaged upon opening the package:

Additional hardware such as clamps, hangers, or adapter pipes may be required for installation and are typically sold separately, depending on your specific vehicle and existing exhaust setup.

5. Installation

The HKS HKS-3106-EX007 is a universal muffler designed for custom fitment. Professional installation by a qualified mechanic or exhaust specialist is highly recommended to ensure proper fitment, sealing, and performance.

General Installation Steps:

1. Preparation: Park the vehicle on a level surface and engage the parking brake. Allow the exhaust system to cool completely. Lift the vehicle safely using jack stands or a lift.
2. Remove Existing Muffler: Carefully remove the existing muffler from your vehicle's exhaust system. This may involve cutting the exhaust pipe or unbolting flanges.
3. Fitment Check: Position the HKS muffler to determine the best fitment and alignment with your vehicle's exhaust piping. The muffler has a 75mm piping diameter.
4. Connection Method: The muffler can be connected to your existing exhaust pipe using either welding or exhaust clamps (butt clamp, lap clamp, or narrow band clamp). Welding provides a more secure and permanent connection.
5. Secure Installation: Ensure the muffler is securely attached and properly aligned to prevent rattles, leaks, or interference with other vehicle components. Use appropriate hangers to support the muffler's weight.
6. Final Inspection: Lower the vehicle and perform a thorough inspection for any leaks, loose connections, or improper clearances. Start the engine and listen for any unusual noises.

Due to the universal nature of this product, specific cutting, bending, or fabrication of exhaust pipes may be necessary to achieve a proper fit for your vehicle.

6. Operation

Once installed, the HKS Hi-Power Muffler will alter your vehicle's exhaust sound. Expect a deeper, more aggressive tone compared to the factory muffler. The sound level will vary depending on your vehicle's engine, other exhaust components, and driving conditions. It is designed to provide a noticeable sound enhancement without being excessively loud for typical driving.

7. Maintenance

Regular maintenance will help preserve the appearance and functionality of your HKS muffler.

• Cleaning: Clean the exterior of the muffler regularly with mild soap and water to remove dirt, grime, and road salt. For stubborn stains, use a non-abrasive stainless steel cleaner. Avoid harsh chemicals or abrasive pads that can scratch the finish.
• Inspection: Periodically inspect the muffler and all exhaust connections for any signs of corrosion, cracks, loose clamps, or leaks. Address any issues promptly to prevent further damage.
• Hanger Check: Ensure all exhaust hangers are intact and providing adequate support to the muffler. Replace any worn or damaged hangers.

8. Troubleshooting

If you experience issues after installation, consider the following:

• Excessive Noise/Rattling: Check for loose connections, improper alignment causing contact with the vehicle chassis, or damaged hangers.
• Exhaust Leaks: Inspect all joints and welds for signs of exhaust gas leakage. Tighten clamps or re-weld as necessary.
• Unusual Vibrations: Ensure the muffler is not touching any part of the vehicle body. Adjust hangers or reposition the muffler if needed.

For persistent issues, consult with a professional exhaust technician.
