Call CARB, they apparently have a list of recognized manufacturers and installers of DPF's that can be retrofitted to older engines. By far your least expensive option at an estimated $15 K last I heard. Don't do anything till the last minute though as they can't seem to make up their minds and who knows what the rules will ultimately be.
