1. Preparation:
   • Ensure the scooter's engine is completely cool.

2. Removal of Old Exhaust:
   • Locate and loosen the mounting bolts and clamps securing the existing exhaust system to the engine manifold and frame.
   • Carefully remove the old exhaust system. Be mindful of any gaskets or seals that may need replacement.
3. Installation of New Exhaust:
   • Attach the new exhaust header/adapter pipe to the engine manifold. Ensure a proper seal.
   • Slide the Polini muffler onto the adapter pipe.
   • Align the mounting points of the muffler with the scooter's frame.
   • Insert the mounting bolts with washers and the spacer/bushing as required.

Key operational characteristics:

• Enhanced Performance: The exhaust system is designed to optimize engine performance, contributing to improved power delivery and throttle response.
• Acoustics: The system is engineered to produce a pleasant sound level while adhering to legal noise limits.
• Heat Management: Exhaust systems become very hot during operation. Avoid touching the exhaust pipe or muffler immediately after use to prevent burns.

Maintenance

Regular maintenance will help prolong the life and maintain the performance of your Polini Black Collection Exhaust System.
