I am looking at the FMF powerpack with the slipon K&N filter and jet kit for $350.. is this a good power adding setup??

 

Well I have the FMF pc4 slip on and the K&N filter.. I dont have the stock carb or motor but I do remeber when the pipe and kit went in it does wake the DS up.. If your gonna beafup the DS you have to start with a pipe and filter, for slipons they are all very close in power.. The other option is getting the jetkit, filter and the end cap.. That will save you about 100 bucks..but it has now spark arrestor for woods riding.. get the cdi next! you will rev out too fast with a pipe, filter and stock CDI.
