headers?

[jeffs400ex]

Does anyone know of some good headers for the 400ex. I am thinking the power bomb headers but if there is a better one please let me know. thanks

I have the Powerbomb. I Like alot. Here's a pic of my freshly built 440ex. I was breaking the motor in on my dyno. Then I dialed the jetting in.

i have herd on this site that the powerbomb header and an hmf slip on are a good combo. i dont have first hand experience but a few people have told me this.

That is true and I have seen Pics of it. I'm thinking of doing that . When I do I'll post the results.

read the post man, this isn't for a 400ex, the white bro's and yoshi set-up is for a 300ex, and will not work on the 400.
