• Equipment: 94 dB reducer insert and spark arrestor included.
• Compatibility: fits original collector or FMF collector (slip-on).
• Engineering: Factory Forward Engineering for mass centralisation and structural reinforcement.
• Compliance: meets AMA and FIM noise standards.

Ideal for riders seeking controlled sound, improved engine breathing, and a lightweight, durable exhaust component. Manufacturer reference: 045700. Suitable for Enduro and Motocross universes.
