i was told by a skunk2 rep that the IM is no better then an itr IM. he said that it takes away quite a bit of low end, mid range is increased slightly, but high end gains can be found at 7k rpms and on. he said it's not worth it unless i get cams that allow me to rev past 8k rpm.

 

Have you checked the official S2 IM thread in this forum? You should probably read through it if not.

To answer your question, it's pretty much exactly the same as an ITR manifold, but made to fit the P72 head.

 

Ummm.... Alot of people love it, just search for "skunk2 manifold" in the integra archives, and there are some odd 120 post on it or something. Some people have told me the abs or whatever that new manifold is, that it is much better.
