Guys im about to buy this header but not sure if its what the guy says it is what do you guys think it is?

 

looks like my stock em1 exhaust manifold with some shitty test pipe bolted on to it.

 

That header appears to be a JDM '96 Spec ITR header or a CTR header. It is a 4-2-1 with a 2.5" collector and a smoother 2-1 merge than all of the normal OEM exhaust manifolds.

If the collector is only 2.25", it is a USDM ITR header. From the pictures you can tell it's no normal USDM sized collector, so it had to have come from some form of Type R vehicle.

Nobody should listen to me...I'm an '06 n00b

 

I was told it was a Jdm Itr header! So is it doesnt seem like the top half is?

IT IS A JDM ITR HEADER!!!!!

It just came from a '96 Spec ITR. Only the '98 Spec ITR had the 4-1 header. The top half of all the B series VTEC manifolds are the same.

 

Mr. Bob i thought the top half should look like this?

Dude...that pic is of a '98 Spec ITR 4-1. The header you are looking at buying is a '96 Spec ITR header. The '96 Spec ITR header is TWO PIECE. The '98 Spec is ONE PIECE.

They look nothing like each other.

 

that would be the 98+ spec itr (jdm) header

edit: damn bob with the quickness

 

ok will both styles of the header yeild the same amount of power?

Both '96 Spec and '98 Spec ITRs were rated at 200ps (about 197hp), so I couldn't really tell you for sure.

 

IIRC, don't the USDM ITR's and pre-98 JDM ITR's have 2.0" collectors? I also think there was an older 96 spec JDM ITR header that had a 2.5" collector (but not the standard 4-1 we usually see). Not to add confusion to this issue...

I'm pretty sure the JDM '96 Spec ITR manifold has a 2.5" collector.

USDM GS-Rs had a 2" collector, but I think the USDM ITR has a 2.25" collector.

USDM ITRs and pre '98 JDM ITRs just didn't have the 4-1 configuration...

 

Damn Mr. Bob

Thanks for your help you guys looks like ill pick this up from this guy he has a great price on it!

 

you might want to measure it first, there will be a difference between the 2.5" version and the others will smaller outlets...

 

Just from looking at those first pics you can tell that it isn't the stock 2" collector.

The smallest it could possibly be is 2.25".

 

how much? is it worth the trouble? why not just get a used JDM DC 4-1 replica

 

dat looks like a CTR header or a pre 98 ITR
both have 2.5" collectors. Mr. Bob is right

 

If only it would fit a d series
