Don't listen to any of them get a big gun eve full system full system allows for better airflow from the engine to the exhaust and produces more power and better sound than slip on. I have it on my 700r and my friend has it on his YFZ 450 we both agree it's the best exhaust out there heres the link....... http://www.biggunexhaust.com/ex_atv_yam.html

why get a jet kit? youll be wasting your money. just buy the jets that you need. also dont get a header becaust thats also a waste. they do notheing on the 350 motors. just go get an hmf, fmf powercore or yoshimura

Don't listen to the fan boys that are telling you to get a particular brand just because its what is on their bike.

The thing to remember here is that just because an exhaust is $400, does not mean it is going to give you ANY more power than the $275 exhaust. Do a search and see that just about all of the exhaust for our bikes put out the same gains. Also, the FMF Powerbomb header is an absolute complete waste of money! Several dynos out there showing absolute no gains, not even to the tenth of a horsepower.

Stick with the one that best fits your budget and is appealing to you. You cannot go wrong with GYTR. FMF and HMF have also both been in the industry for a very long time and have proved their products.
