You could find a set of Mazda MPV headers. Instead of dumping into one bank like the stockers, these are more tubular and at the bottom of the front header the stock one does a wierd crush 90 degree bend where the MPV do a smooth manderal bend. Also they don't have a catalist in them. You will need to weld a second boss into the y-pipe for your MIL for the MPVs don't have the one in the header. Should game some good exhaust flow with out spending an arm and a leg.
