I have a 1999 artic cat 300 4x4 and was wondering how i could get some more speed out of it, i havent found any pipes will fit, i do have a uni air filter, it works great in 4x4 for bushwackin. but not much on the speed and touque department, except in low it has good power thanks! Also is their anything that i can do to make it more mud friendly? Larger Tires? Lift kit? thats what i really bought this machine for mudding and deep water, is thier any way to build or buy gaurds for the front diff so when stuff hits it it dosnt break somthing.
