The fit of the spark arrestor is excellent and I didn't notice any loss of power, although when the 300 is trying to take off like a rocket ship at every opportunity I may not have noticed if there was a slight change. My ear did not notice any choke in the throttle sound between on and off.
While not USFS approved as mentioned, it is labled appropriately and honestly I see no difference between the screen material between the Spanish Fly and the FMF pipe on my WR450.
