Anywhere to buy fmf powercore 4 slip on for 300ex

[wantablaster]

I already have an fmf megamax system and the powercore 4 is suppposed to be better and this will mount up to my fmf header for the megamax without any cutting like I would have to for an hmf, and I dont want to spend the money on a whole new full system. So does anyone know where I can buy just the powercore 4 slip on for my 300ex everywhere I have looked just sells the complete systems.
