I have heard that it will be available by next spring. Not really sure if it will or not. I have only seen info of it in the book, and in a magazine. The reason I say I am not impressed with the tfs manifold is what I was told how it was going to be. Then I heard from another guy from tfs later and he said that it will just barely outperform the bullit. The price I have heard for the tfs is that it should be around $700. The represenative gave me his number and told me to call him soon. I will talk to him pretty quickly and try to get some more information such as price and a possible dyno on it. I know that they tested it with a set of patriot heads and a set of heads from tea. He did not know what stages they were, but is finding out. Tfs is only prommising bullit performace at a little cheaper price.The pi does perform well for an oem manifold, but everyone around here is tired of problems out of them. People say that the new ones will not crack where the coolant goes in, but they will. I have already had 3 on my car since I had it. When I bought it it had the npi manifold with an aluminum crossover on it. I am not putting them on wrong or anything.</blockquote>
