if your going to be riding in the dirt, i would have to say a pro design foam filter kit over a k&n. fmf fatty's are real good pipes, with an affordable price. yea i would agree that paul turner midrange pipes are the best for low-mid , but if u dont have a big budget then i wouldn't get them, fatty's will perform good enough. for more low end, get the Trinity CV single carb setup w/ a 35mm carb. you can get your head milled to increase your compression, or get an aftermarket head. if you looking to get more traction, you can get your stock swingarm shortened -2 by Quicksand Motorsports, it will hook up more in the dirt. if you dont like the stock banshee suspension, some aftermarket shocks should help out.
