Last I spoke to Mike he didn't have any more front sections and didn't plan on making more. He did say if there was enough interest, he would do it.

Anyone interested in one? The front section is the part that bolts to the header and has the expansion chamber. They are $225 normally.

Supposedly they will bolt up to the other headers than the one Mike sells, I am told it will bolt up to any that have the RB style flange.
