hi, i have a 2003 arctic cat 250 2x4 and i want some more power in it, one of my friends told me i should look into getting a new exhaust system, i dont know much at all about this and was curious if anyone knew of an exhaust system that would help my fourwheelers power but not to expensive, and also after i get one, he said something about a jet system and air intake? im not familiar with this, do i need one when i get my exhaust, thanks alot for your help
?

a new pipe will add a nice gain and you will need to rejet because of the pipe. a dynojet kit will help with power as well. if you add a high flow air filter you will have to rejet as well.

ok so is this dyno kit an exhaust kit or what, will it replace my muffler, and if i get this is need a new air intake? do you recommend any kind, what all would i need? annd the dyno kit, is it a pretty good one, i looked it up, do u think it would help alot in my take off?and what about sound, i like a muscle sound would it change it at all? thanks alot

ooh ok so your saying after i get the muffler or exhaust kit i need i need the dynokit with it, ok, and i looked i cant find any that says it will work with a arctic cat 2003 250 2x4
