well i recently bought a used stock header off craigslist, the dude claims to be a jdm 96spec itr header... paid $90 for it w/ heatsheild but my question is..

whats the collector size....

what im reading is 2.3" collector, and 3" w/ donut gasket..
the header is a 4-2-1, the length is about the same size as b16 header... has the o2 bung.

what u guys think..?

 

pics?

 

USDM models have a 2" collector. Pretty sure JDM 96 spec is 2.25".

 

it's 2.5", uses the same gasket as the s2000

they resemble a gsr manifold on steroids.

$90 is a pretty good deal for one of those since they can actually make power. they just happen to be heavy and out of fad.

 

I guess its the 98spec+ thats 4-1, the 4-1 jdm itr header is suppose to be better then the 4-2-1
