I agree with the FMF pipe we have the same mods on ours & it works great in the dunes & the mountains . Alos it is not so loud it blows your ear drums out . Aother plus it came complete for about $265.00 from rockymountainatv.com . One other thing you will need is a pipe guard it has a tendency to melt your pants , boots , leg etc !

 

I run a DG triple chrome pipe on my 300ex. It gives good noticable power and only costs about 150$ for the complete bolt on assembly. The only thing though is that when you let it idle with the choke on or race it too hard the pipe will turn blue. But, the shiny crome pipe sure does stand out going down the trail

 

Call the manufacturer and ask for dyno test results. Its easier to decide what to buy when you know where each system comes on strongest. Then you can make a better decision based on factual information. I have white bros. I have heard several people having problems with the fit of supertrap. When they call supertrapp the answer given is "our jig must have slipped" Then they want you to pay to return it to get replaced. Not a very proffesional response from supertrap.
