aka Hyper Rev 4...
i like the HKS one since it has some extra pipes looping around to give extra torque....

is the HKS headrer a 4 -1 design (looks like from the picture)? Will improve power at the top end of the rev range.

The 5Zigen is a 4-2-1, more torque, more low down power but not the same effects top end.

In theory anyway.

Buy the fujitsubo 4-2-1 manifold! :bow:  :bow:  I have a friend with a HKS manifold and my car was quicker than his (I have fujitsubo on my car). We had the same mods as well.

You think the Fujitsubo would be best? I would be tempted by this because it would match the legalis r exhaust. Have you had it long? Any complaints?

I have it for 6 months now. No problem,and it's really good! I think you must buy this. 4-1 manifolds,will not help you at all


a 4 - 1 would more than likely suit the 4a better, but only if your tracking it alot. in terms of every day driving the 4-2-1 would be better.

Either Fujitsubo or 5zigen, as said above they're both exhaust specialists so more research has prob been put into them!

Id prob go Fujitsubo coz of the price difference! ;)

Right, sorry for hijacking the thread but was searching around the net for parts and im after coming across a company that makes custom manifolds for the ae111 .......... Now the price sounds good- $299 but would you trust an unknown company to make one?! I should also add that its a 4-1 design and they advertise on ebay which is kind of a warning sign!!!

Yer Thoughts????????? :idk:

Can't vouch for HKS or Fujitsubo...as I have only ever had the stock previously and now the 5Zigen...., but the 5Zigen certainly gives good pull throughout the whole rev band...

Don't know what the actual gains are, as I didn't get any before after dyno reading, but it is better than the stock header...only thing is it gets hotter due to being stainless, so probably better getting good quality wrap to keep the temp under control..

well ill let you all know about my hks racing once i get my link pip made up. if any have actual read the jamica wheels testing off manifolds they say that the levins love the 4-1 and that there is very little diffrence between torque.
and if you notice th link bars on the hks from what i know they are to increase the scavange effect causing it to make more torque. and for the mad money it is i would say theres anlot of development gone into it.

How do you find the difference since getting the 4-1 in your car?

On a separate note I wonder why the guys fabricating the custom manifold didn't just try to make it to the Cusco spec or I guess getting an Original to copy was the barrier :D

That would of being a good idea ahri is 4-1 the best then would the apexi one be good parrot if fixed right?
Offline Profile Quote Post Goto Top
 
The Parrot


well the apexi is a 4 into 1 yes but is what they call a spirl 4 into 1 it is a very good manifold if fixed right.

yup on the cusco yes getting the original and i would say its very awkuard to copy as its not a normal design.. it has a ball at the bottom of the 4 into 1 section i would say not fun to manifacture

so far im chuffed with the hks racing. little bit of adjustments left to be made. but. 2500k and below its down on a bit of tourque but after that it rips. the car is still very drivable.

it seems in the 4-2-1 range its either fujitsubo ex header or HKS super header.
Now iv heard these are identical but there are some differences in design?
according to RHDJapan the fujitsubo one makes a nice bump in HP as well as a small bump in dB
anyone dynoed a HKS before and after to compare? and apparently its quieter than stock. why is this? something to do with the flex pipe?
there must be some sort of difference between the two performance wise

I've heard if you remove the baffles from the stock manifold then it's the same as an aftermarket 4-2-1, anyone done this?
Offline Profile Quote Post Goto Top
 
The Parrot


dosnt make much diffrence its to do with sound. when you actual look at the full 2 into 1 section on a standard manifold thats were the main restriction is.

bmchi theres very little between them.
jamica wheels has done the dyno runs.
there nothing between them really. as its all down to formulas for flow rates.
they use to say the fgk was the better one due to it being cheaper but i think both are pretty much the same now.
