I think found a good setup.

Sometime at the end of the month or early into the next i'll be buying this exhaust system:

Ironman Series Carbon Fiber FULL for 2005 Honda 400EX
Jet Kit: Comp Kit by HMF.

I plan on getting a 15t/36t combo after calling around and seeing if thats a good combo to go with as far as increasing top end goes. I want your guys opinion on both the exhaust system I chose and if the sprocket combo I plan on getting is right for what I want, Thanks :D

HMF is great exuahst just get it off e-bay the guys on there are cheaper and have great service :devil: As far as the sprocket set up that will give you more top-end.I run mine for low end so not sure what that sprocket set up will do.

yea im about to get an hmf. I have the primary drive 15/36 combo from rocky mountain. It does change the top and its really noticable. I stripped my stock sprockets. so i had to get those. but as far as the hmf im about to get 1 from worldwideperformance1.com. Its the cheapest place i have ever found...even cheaper than ebay. there 199.95. plus shipping. hope that helps.
