Im looking to give my 05 prairie 360 more power. i found a new cheap pipe (hmf) for $227 seems good for the money and also comes with jets, it says its a 7hp increase. is this worth it? and doi need to jet it?

 

yes you need the jet kit...if you are going to have more exhaust flow you NEED more fuel flow. it would probably be a good idea to get an aftermarket air filter as well. the hmf pipes are very under rated IMO. good tone and larger exhaust capacity. it will give you power; but if your looking for speed for your 360, not gonna happen... 360's just are not fast. good luck and the pipe and jet kit are worht the $

 

the pipe comes with a jet kit i believe. and i have a kn kilter

 

sounds like your good to go
