FMF’s oval-to-round-constructed Factory 4 ATV exhaust uses military-grade titanium and is offered in either natural or anodized blue finish. It has a modular end cap that enables adjustment of the sound level and powerband. New for 2004 is the modular ATV exhaust port flange, which FMF says offers a better seal, transmits less vibration and puts less tension on the ATV exhaust system. A ATV Power Up jet kit and a “remove before flight” wash plug is included.
