I have a 2001 scrambler 400, and I'm getting a RCR stage 1 kit with a HPD trail pipe, Should I use the Air-box-mod kit that it comes with and the Uni Air filter, or should I put on a filtercharger with outerware? I do mostly fast trail riding, and play racing and drags, but I'm 15 an I do some pretty nasty mudding when It rains alot. Should I get the Charger and just put on my airbox & stock filter when I go mudding or what?

 

keep your snorkle air box unless your not gonna ride when its raining hard/ snowing/ in snow/ in water/ in mud, ect. ect.
