well i just finished my y8 manifold swap onto my car, and i just wanted to say to all the d16y7 owners, that this is a good, cheap swap with a lot of top end gain, granted you have seen what the y7 intake maifold looks like, its soooooo resctrictive, i also put on an ebay intake with a giant k&n on it, top end is sooo much better, and the car doesnt fall flat on its face above 4 grand like the old one, and this can all be done with a new intake for about 100 bucks easy......just giving some good cheap mods for us stuck with the d series, now if any1 can tell me if headers and exhaust will give me any gains BEFORE i do my mini-me swap, caz if they dont do anything except sound like crap, im just going to wait till after my mini-me......thanks guys and good luck
