difference between USDM ITR header, and other USDM header?
Does anyone know if there is a difference between the USDM type r header and other USDM headers, ie: GSR< GS, LS, RS? I got a hold one a set of US type r header, and i don't want to go threw all the trouble to put them on my LS if they are the same.
Thanks

You can save some time by only swaping out the lower half of the manifold. The upper portions are the same.

What is the different with the lower portion? Is the collector larger in diameter? What is the size if the stock ITR manifold, collector?

The collectors are all the same OD (2.00"). There was a <U>slight</U> difference between the ID's of the ITR manifold and a B16A manifold when I measured the two, and although I've never measured the ID on an LS or GS-R collector, they are almost certainly within fractions of each other, if not completely identical. The major difference (if it can be called major) between the two manifolds is in the 2-1 merge, which is slighly better on the ITR.
