What head pipe is the best for the 400EX

[400EXdude]

Im gonna get a new headpipe for my White Brothers Slip on...and i wanted to know what would give me the most power and the best sound? Thanks

I have a Sparks x-6
for $50.00 + ship
Excellent condition.

The sparks header wont fit with the white bros silencer... For 50 bucks though thats cheap, I would just get that header, sell your WB and buy a silencer from sparks!

dont you have to get a different slip on with the white brothers, differents bends in slip on, pro meg, s bend? my e series s bend slip on went to shreds and i want to go to a different slip on but i dont know of any other slip ons that will bolt up to the wb header, it is about 5-7 inches shorter than the stocker
