Thanks a pretty general statement with no facts to back it up. Don't just go and "hog-it-out". Depending on your set-up the stock or Skunk (which is a stock copy) work just fine as is.

I spent alot of time dynoing different manifolds (stock, extrude-honed. skunk.....) as weel as big bore throttle bodies and most result in very little or no gain at all on a ITR motor with basic bolt ons. (header, exhaust, intake,cam gears.....)

In some cases it held the power up top longer, but did not increase power at all.

I am pretty sure that the skunk2 is just a copy of the itr as the others stated. This is a good option if you have a gsr and want to get rid of the secondary butterflies. Since a itr manifold won't bolt on, this is the next best thing.
