any aftermarket pipes fit the HMF slip-on?

do any aftermarket headpipes fit an HMF slip-on? i assume that HMF headpipes dont fit the slip-on since ya have to ship the slip-on to them and have them covert it over. does the FMF powerbomb fit it? how about a WB header?

I bought my FMF off rockymountain.com just a few mins ago :)
