Maybe that’s only rhd? Who knows. But this is the header they are selling for the system now. They are back ordered till June. Maybe they will do the upgraded header then? 

I hope it works  

 

 

 

they're all only RHD.  They just happen to fit LHD cars.  If you order the complete system new, the header above is what you get. Its got the part number lazer cut into it.

Do you have it? 

[duffymahoney]

Fitment is awesome. I can’t believe how well it tucks. The header must be correct or at least made for the newer system.   

Its on and mostly tight. I might tweak it a tiny bit. The exhaust tips are ever so slightly off angle and one more exhaust hanger and it’s done. 

I tried working from the back forward. Which didn’t work. Then I tried middle forward which didn’t work. Engine back worked great. I love learning from mistakes. 

[Jason240z]

Yes I do.

pleased for you!

It’s useful that the older style manifold does fit, it’ll be interesting to see how it fits at the front (height) compared to the new style of manifold it’s designed with. Also the general alignment.  

Can you measure from the top of the engine flange to the bottom of the first join?

Here you go

To prove I've not been going mad.

 

you have part number 510-1535, lots of pics about if you google the part number. Fujitsubo call this the EX-mani.

Part number above is 510-1536, google that part number.  Fujitsubo call this the 'super ex-mani'.

The data they provide here is with the super ex-mai, and the low corrospondence exhaust.

I never thought you were going mad.  But we know that this header works and was designed around the new system (510-15037) .  I can measure but I don't see a point.  It couldn't be higher.  I think they maxed out the design to a crazy tolerance for tuck.  Fitment looks basically identical to the pictures posted.  

 

I will be curious to see how the 510-1535 (ex-mani) fits around the steering and su's.  I like the look of the newer header ex-mani more then mine, but it wasn't for sale when I ordered mine (at least what fujitsubo told me).  Looks like the changed the tubes a lot.  Same size tubes in both headers. I would be curious why.  Probably some sort of flow improvement I would guess.  I also don't see it listed on their site yet (which isn't easy to navigate), I am willing to bet it launches fully June 1st.  When the backorder will be done.

My exhaust says it's " It is only compatible with safety standard conformity product 2 seater exclusive Super EX (510-15037) It is incompatible with original EX Mani and Super EX (510-15036)

 

So I am guessing the only option is 510-1535 and 510-15307. 

 

Looks like the 510-1535 is equal length header.  Which is pretty awesome.

Got it installed.

 

Here is my overall quick review.

It's pretty quiet 800-1600 rpms. Almost weirdly quite.  I have a bone stock 2.4L so that has something to do with it.  Above 3k rpms it starts to sound like a z.  But not really throaty.  Again that is probably from being a bone stock motor.  I will try to take a video and post it.  I was hoping for more of the sound people have in videos, but I guess I have no idea what rpm that is at when the rev.

New Fujitsubo header is in! Well mostly. It’s coated in chromex ceramic coating inside and out for heat reduction.

Clears steering well. Also my series 1 heat shield could be bent up to clear

Hi Duffy - looking great and love the feedback.

Couple of questions and apologies if already answered somewhere :

1) How is the fit with the block-breather tube (did you have to bend/shorten/modify the tube ?

2) Sound-related ; yes, your stock engine will have less compression than a modified engine but it should still produce some great 'noise' - what internal diamater primary pipes have you chosen ?

My block breathing tube was already cut and a 90 is there.  It would clear it fine, maybe 1/2" clearance.  I bought a NOS one and will install this week.

 

There wasn't an option for internal diameter.  So I got whatever was sold.  I assume it's my motor related for the noise.  She isn't running correct yet.  Also she is small at 2.4:)

So - did you measure it before fitting ? Can you tell me the internal diamater from the invoice perhaps ?

Engine size doesn't make any difference to the sound (well, not very much anyway) but flow-rate/velocity does and bigger diamater pipes mean less velocity.
