Has anyone had any experience with the FMF Powercore 4 using the powerbomb or the Hi-Flow headers on the 400 EX? Please let me know what you thought of them.

most people who have tried the powerbong have had good success.

I had a friend that put one on a 03 400ex, it was one of the strongest close to stock bikes I ever rode.

I have a powerbomb with the Powercore 4 and love it.
