hi,

anyone got a pic of the OEM B18C6 EDM header without the shield, as i am meant to have one on my B18C-R (the original 4-1 was damaged ) but it doesnt look right. Will try and get a pic of mine up, but want something to compare it too

 

Here you go ; one OEM B18C6 EDM header:

 

the upper 1/2 is tubular steel vs. the cast iron unit that the US gets...
the lower 1/2 is still the same as far as I know.

sorry.. I don't have any pictures.

 

If you really have this EDM header on your JDM B18C, remove it quickly. It's useless. Primary tubes are 40 mm OD or something.

The collector is 42mm inner diameter:


Stock EDM b-pipe has 45mm ID, just FYI:

 

The B-pipe is the same as the USDM B-pipe. If you remove the bottleneck, it's also 57mm OD.

 

wow, awsome info guys, thats what i have

I do have a UK ITR mani on a B18C-R, as i spent all my cash on the swap, and got one real cheap I also only have a 50mm ID exhaust system, again as it works and was already there.

I spent the money finishing off the chassis (Coilovers, ITR sways etc) and tracktime, as 180-90bhp is fine for now, just learning the car, as its a big change from 130bhp and no LSD. More power will come when i can afford the real thing

Out of interest, how exactly do you 'remove' the restriction, take its a dremel job

you have to cut the first ~9cm of the cat-back off and install a 'taper cone' of some sort.
