The innovative rear end cap allows for easy installation of tuning tip inserts or a spark arrestor, which can be secured by simply removing four screws, providing flexibility for different riding conditions. The muffler includes a QuietCore 94dB insert, enabling riders to adjust noise levels and meet sound restrictions without compromising performance. Additionally, the spark arrestor is integrated into the muffler design, ensuring safe operation in areas with fire restrictions. This system is designed for ease of installation, durability, and consistent performance, making it a reliable choice for serious riders seeking to optimize their motorcycle’s exhaust system.
