I saw Evolution Performance has them for sale. $799 is what they're selling them for.
It's good that someone makes one now. Only worth it if you have cams, heads, spray, turbo, or blower though. On an NA car, they won't make enough power to justify the cost. On a car with only intake and tune, it made an additional 15HP. But it doesn't have the CMCV's. So if you already have CMCV's, you can take about 7 HP off of that, meaning you'll really only gain about 8 HP for $800. But, if you have heavier mods, then it'll definitely be worth it.
