4. Installation

The Borla 40364 ProXS muffler is designed for weld-on installation. Professional installation is recommended to ensure proper fitment and sealing. If clamping is preferred, use 3-inch wide band clamps (Borla part number 18004) for secure attachment.

2. Fitment Check: Position the new Borla muffler to determine the optimal orientation and fit within the exhaust system. The reversible design allows for flexibility.
3. Cutting and Alignment: Carefully cut the existing exhaust pipes to accommodate the new muffler. Ensure proper alignment for a straight and secure fit.
4. Welding/Clamping:
   • For Weld-On: Weld the muffler securely to the exhaust pipes. Ensure a complete and leak-free seal.
   • For Clamping: Use Borla 3-inch wide band clamps (part number 18004) to secure the muffler to the pipes. Tighten clamps evenly to prevent leaks.
5. Final Inspection: Check all connections for leaks and ensure the muffler is securely mounted and does not interfere with other vehicle components.

5. Operation

The Borla ProXS muffler is designed to deliver a performance exhaust note that is noticeable but not excessively loud. It typically provides a deep, rich tone under acceleration while maintaining a quieter profile during cruising or idle. The sound characteristics may vary depending on the vehicle's engine, other exhaust components, and overall setup.

6. Maintenance

The Borla ProXS muffler is constructed from T-304 stainless steel, known for its excellent corrosion resistance and durability. Minimal maintenance is required. Periodically inspect the muffler and exhaust system for:

• Loose connections or clamps.
• Cracks or damage to the muffler body or welds.
• Corrosion or rust, especially in areas where the exhaust system connects to other components.
• Ensure proper clearance from other vehicle parts to prevent rubbing or heat damage.

Cleaning with mild soap and water can help maintain the appearance of the stainless steel finish.

If you experience issues with your Borla ProXS muffler, consider the following common troubleshooting steps:

• Excessive Noise or Rattle: Check for loose clamps, hangers, or contact with other vehicle components. Ensure all connections are tight.
• Exhaust Leaks: Inspect all welds and clamped connections for signs of exhaust gas leakage. Leaks can affect performance and sound.
• Unusual Vibrations: Verify that the muffler is securely mounted and not touching the vehicle's frame or body.
• Sound Not as Expected: Exhaust sound can be subjective and influenced by other exhaust components (e.g., catalytic converters, resonators) and engine type. Ensure all components are correctly installed.

If problems persist, consult a qualified automotive technician.
