I believe Rocky Mountain ATV has them for around that price. That's where I got mine. :)

Thanks a lot, that was the place i saw them! Any other suggestions for me. I just got a new 400EX last week and am looking for a few mods to give a little power boost. I mostly trail riding. I was thinking wb e-series, jet kit, and i bought the airbox vents to put in the lid. Let me know what you think, thanks!

Don't forget to pick up an Outerwears filter cover for your new K&N...they're only $10 or so from Rocky Mountain.

Also, you may want to look into HMF exhaust systems. They seem to be the new favorite. I know I'm getting one! :D

Arent the hmf silencers more for modded engines? I went to there site and it says the slip ons work best on modded motors

[TORO1968]

I believe they work well on both stock and modded engines, though, you'll see more of a benefit from the exhaust the more modded your engine is. I'm still getting a full system for my basically stock 400ex. I'll add the rest of the mods later! :D

Don't get the e-series:mad:

I heard good things about the E-series! Did you have problems with it?

with the hmf site saying that the slip on works best for modded motors...i think that's a typo.
