i am going to get a new exhaust for my 400ex. i was thinking about the yoshimura comp series full exhaust. does ne one have this and what do they think of it. also is there neother exhaust that u think might be better i wanna keep the price under 450.
another thing is what jet kit is the best to buy or does it not really matter

Most of the people ive talked to that have a Yoshi says it restricts the motor more then alot of the new systems out now...If you want under 450, id suggest HMF

I recommend the Hetrick racing pipe. For the money you can't go wrong. Its ceramic coated and they give you the jets you need for it.

big gun is a lot louder than stock. not much power gain over stock. hmf makes a good slip-on.

You can get HMF from C&D.

They do have the full system, but if you don't have motor work, I wouldn't recommend it. The head pipe is huge, compared to most others.

The slip on runs a little over $200 and is very nice, I like mine alot. But is defiantly alot louder than stock, but also a better sound.

They also offer a quiet core, if needed.

So the word is to not install HMF full exhaust on a stock 400ex? What will happen if I get the full HMF and jet the carb and get K&N air filter. Will that be ok?

It will be fine, but it won't have as much of an effect on a stock motor, to lets say you had a 440 and went from stock headers to the big gun full system. If you don't have motor work, and arn't planning on doing any, just go with a slip-on, filter, and a jets.

you won't be disappointed with lrd or hmf. both will have similar power gains. i would probally get what you can get the best deal on or which one you like the looks of better.
