Hey guys. I have an integra GS-R, but I bought a new cat/exhaust that is a direct bolt-on for an ITR. I was planning on going ITR specs from the header back. My engine is a stock GS-R with an intake. No internal mods to the engine. I planned on getting a DC 4-2-1 header for an ITR, but it is on backorder till god knows when. Does anyone have another suggestion that would be as good or better than a DC 4-2-1? I don't want to go much bigger than 2.25, as my cat is 2.25"

It has to bolt up with the stuff I already have.

I believe the Mugen 4-1 is offered in a 2.25in collector size.

I have this and I will be willing to sell it, if you want?

I have a feeling anything Mugen is going to be out of my price range. PM me though if you want to offer it up.

Does the stock ITR header have a 2.5" collector? And is the USDM a 4-1 like the JDM ITR header?

USDM is 2.25
JDM is 2.5

USDM is not a 4-1 design, rather a 4-2-1 2 piece design. The JDM 4-1 is a one piece. Hope that helps.

Is the USDM ITR header any better than a stock GS-R header?

The GS-R is a 4-2-1 two-piece as well.

Hope that was not aimed at the difference in GSR to ITR header.
