The FMF Hex Q4 Muffler is engineered to optimize exhaust performance while maintaining strict acoustic compliance. By incorporating internal baffles, chambers, and advanced sound-absorbing materials, the system accelerates exhaust flow with minimal power loss. This design ensures the muffler operates well under the 96 dB sound output threshold on most machines, satisfying rigorous sound requirements without compromising engine efficiency.
Designed for durability and regulatory adherence, the Q4 Hex features a U.S. Forestry Approved spark arrestor. This component utilizes a maintenance-free, stainless steel spark arrestor screen to provide reliable protection. Please note that the Q4 Hex Exhaust is exclusively available for the specific "Current Models" listed in the product inventory.
