If you change the intake and add pciii you should go with a full exhaust...that'll give a significant increase in hp...probably run in the $1k range but well worth every penny, check out FuelAtv...

best mods in my opinion are full exhaust, new intake (stock one very restrictive), and a PC3.

Everybody insists on a full exhaust.... The restrictive part of the exhaust on the KFX is the muffler, not the header/mid pipe. There's no harsh bends, no baffles, it's a decent size diameter, and it's higher quality than a lot of the aftermarket pipes you'll see. (Titanium vs stainless)

The intake, however, IS pretty terrible. That weird rectangular useless thing they put in there is laughable. Can't flow much air through something the size of a quarter, can ya...
