JDM 4-2-1 ITR header with 2.5" Collector???
Is there one out there? I thought that the US ITR headers were 4-2-1 with a 2-2.25" collector and the JDM ITRs have the 4-1 with 2.5" collector. Is there a ITR 4-2-1 with 2.5" collector? If so what are the size of the primaries? TIA.

You mean stock? There are plenty of 4-2-1 aftermarket 2.5" headers.
The '96 JDM ITR has a 4-2-1 2-piece 2.5" header....

Yeah, I meant stock off the JDM ITR. So there is one then. Does anyone know what size the primaries are on that header? And what's size are the primaries on the JUN and Toda 4-2-1 header? Thanks again for your replies back.

You can't compare the sizes of the primaries, because the stock '96 JDM one is made of cast iron which is thicker. At least you can't compare the OD (outer diameter). The primaries of most aftermarket headers are 45 mm OD. I don't know the OD or ID of the stock JDM '96 header.
