Hey my friend has a 2002 honda 300ex. He has a FMF pipe on it. What would be the best mods you could put on it to give it more power?

 

Did he do a rejet with the FMF muffler??? You would be surprised how many people buy a muffler and don't rejet and wonder why it isn't superquad.

Hope he did the header at the same time as the muffler. The stock header is pathetic, and when I bought a PowerCore IV muffler for mine, FMF included a free flowing header at no extra cost!

Open up the airbox (EHS Racing Outerwears lid), and get a more free flowing air filter (UNI or White Bros.).

And.....a rejet of course.....
