I have a 2000 400EX with a Yoshi slip on, on it and I love it, it gave my EX alot more power I think. I would not buy an FMF but thats up too you, 3 of my friends have one and all 3 have fell apart already. I looked at the White Bros. too before I bought mine and I liked them also, espically the new R-series it looks awesome.

 

FMF to me is all hype

i'd go for the full white bros or full Yoshi system

 

I would say to go with the WB E-Series. They seem to have the best quality and performance for the money. And also FMF is not the most durable pipe.

 

Yosh one of my friends has one.And its up to par with mine. Make sure you get an air filter too.

 

I just ordered a White Bro's R series with the Promeg header pipe. I should get it next week. My philosophy when choosing a pipe is to go with the company who has the most experience with 4 stroke technology, White Bro's. They have been building big thumpers for atleast 15 years. I trust their R&D. I do believe that the other manufacturers of exhaust pipes (FMF, ProCircuit) just saw a market and put out a pipe without truly doing any homework. I should have some dyno numbers for this pipe in a few weeks.
