Being it is just a "log" manifold I would agree that it doesn't seem like it would have much of a gain if any over a stock manifold. But, a lot of times you can't judge a book by it's cover. I would be interested in seeing the dyno test with the same motor in both tests, not just two cars that raced at a track that are supposed to be the same. I am interested because I am looking for something for my son's truck.
