To answer your question, likely because of the AFM valves interferes and would have to added into the kit which would probably double the cost. Don't know for certain just speculation based on what I seen when I tried to use them. I ended up sending them back and changing the entire X pipe.
Either way, It's a waste of time, effort, and money until your are making A LOT more power than stock.
