but...i measured the collector and only got 2.25"...wtf did i get...

 

can you provide pics?

2.25 is def not a itr

 

yea when i get off work i'll post up some pics...but **** man **** me off...i was in a rush so i didn't measure the collector...then when i got home i measured it and was only 2.25" across...how can you tell if its oem or a replica...

 

is it a 2pc or 1pc header?

where you get it? how much?

 

its 1 piece 4-1...i bought it off craigslist for $200

 

link to the thread?

 

so who else makes replicas that have a 2.25" collector...cause i think this one is not a jdm one...fawker jacked me i think...

 

I think Megan or DC might have them in 2.25

 

was it rusty or old looking?

usually,

black header = aftermarket

polished = aftermarket

 

naw it looks exactly like the jdm header. bronze looking...even came with the upper heat sheld that made it look completely stock...

 

usdm itr

 

usdm...has a smaller diameter then jdm itr header...so im guessing its a usdm?

 

usdm is also a 2 peice 4-2-1...

he has a 4-1...

 

95-97 itrs came with the 2.25 collector on their 4-1's when i say 95, i mean 96, but the 96 itrs were around in decemeber of 95, so you get my drift.

so you saying that i got one of the older model itr headers...cause yea it is 2.25 diameter across the inner tube...damn...

 

Get the 2.5 collector mod.

 

yea i'm planning on moding it now...i hate it that i got the wrong one but yea i guess i'll have to buy the guys at work lunch for them to make me a collector flange and i'll hammer out a 2.5" stainless steel pipe to make it a 2.5" mod...

 

You got the USDM ITR header which is 2.25" collector that matches the stock 2.25" cat back exhaust, and is CARB legal. What you wanted was the DC JDM 4-1 header with the 2.5" collector and it is not CARB legal. Actually any 2.5" collector header isn't CARB legal as far as I know.

no i got the 96-97 jdm itr 4-1 header...which is also 2.25" now...usdm's do not come in 4-1 i believe...

 

the jdm 4-1 itr header have a 2.25 INSIDE DIAMETER collector!

No you don't. The 95-97 ITR has a 2 piece Tri-Y header that is the same as the one on all US ITRs (shown below). I know because I have one in my car right now. You probably have the real deal, but your not measuring the outer diameter...

 

I think where all the confusion is coming from is the fact that we don't know if you are talking about the stock cast iron manifolds (2 pc), the aftermarket (1 pc) 4-1 OEM replica's which are supposed to be slightly better than the OEM (1 pc), or a DC (DC Sports) 4-1 Type R header (2.25" collector), or the DC JDM 4-1 Type R header which has the 2.5" collector. Now outside of all these headers I mentioned, are a number of other manufacturers making their own versions of "JDM 4-1's" like Megan and Vibrant, EBAY, Password...etc...etc.. It would really help if you could give us the full name of the header you got as well as a pic in order to accurately tell you what you have.

 

where are you measuring? Its 2.5" OD. Most exhausts that are advertised as 2.5" or 3" or whatever are measured OD.

I just measured my JDM DC 4-1 with a sliding caliper and I got 2 7/16" inner diameter and 2 9/16" outer diameter. So 1/16" less than 2.5" inner diameter and 1/16" larger than 2.5" outer diameter.

 

we dont talk about a oem honda jdm itr 4-1 header??
