I am looking for some performance upgrades for my 300ex. I recently purchased a white brothers e series exhaust which I love. I had a K and N filter on it already. I am looking into cheap performance upgrades. Would a rev box do me any good, or would that possibly cause more harm than good, the machine is stock other than the pipe and filter, but I don't ride enough to upgrade to a new machine. Let me know...what I could be looking for and the price range to expect...thanks!!

 

I wouldnt go with just a rev box, If I was going to get serious I would atleast to a cam (200 plus labor) or a good performance CDI box.(I think about 250-300)

If you dont top the 300 ex out all the way and are mainly riding trails you could look at changing just a sprocket(the 300 is chain driven right?)(probably 20-30)

 

did u get the full exhaust or slip on because the 300ex's have such a small header
