Hey everyone. I did some research on here about the above and found this:

Now it says that I would need an LS header and Cat for the ITR exhaust to fit on my '95 GSR.

This may sound like a DUMBASS question, would getting the USDM Type-R header and CAT be the same thing instead of getting the LS ones. Sorry for the ignorance.
