What is the best exhuast pipe to put on my 91 250X

 

id go with the fmf megamax i put one on my 300ex and gave it and enourmous amout of bottom end power but if u have to money go with the white brothers

 

get the whit brothers it adds alot more power and sounds great, the meggamax sucks you haev to take the disks and sparkarester off to get good power gains

 

I have the FMF megamax II on my 92 250x. I love the fact that you can tune it by adding/subractings discs, it isn't a big deal at all to loosen 6 allen screws. It sounds great and isn't too loud, but not too quiet all the same. I tried supertrapp's model but I wasn't impressed with the results. I don't know much about the white bros. kit so I can't say yey or ney on that but the FMF kit comes with silencer and head pipe all in one kit so it's a good deal. Defintely re-jett the carb and get a K&N air filter and also get an new airbox lid with precut holes. All of this will add some ummph to your quad.
