why do you say for a ITR or LS? Whats special about it, shouldnt it fit any?

That's just what it says on the box.

The stock header outlet on the usdm itr is a 2 1/4 and the jdm itr is a 2 1/2 I don't know what the gsr is. Since it includes ls on the box I assume that the ls is also a 2 1/4 and the gsr would be diff but you know what they say when you assume. Hope that was some help
