4-2-1 headers, what brand is good at reasonable price??

[TODA AU]

i been readin this thread all the way from page one, and im also trying to find the best headers to cat back system setup for an EK4, at the moment, i like the idea of Toda headers and cat with a mugen catback exhaust .. and sorry for being noob, but is it possible to fit Mugen B16B (ek9) parts as in the air intake, headers, exhaust cat etc, into the B16A ek4? without having to modify the parts themselves ? because if i can, i would like to have mugen from air intake, headers, all the way to exhaust.

Yes,
The only issue (small as it may be) will be that the headers will be 7mm lower than usual.
Every part will fit, no problem.

oh ok, thanks, and what would the downfalls and good things to having the headers 7mm lower then usual be? the air filter, catback and exhaust system fits, its only the headers lower by 7mm? and would i have to swap the AUDM cat out and put a JDM cat into it before i can fit the system? cos my brother had to put a JDM 98 onwards cat into his DC2 before he put his mugen catback n headers etc, he said he did it so that he didnt have to cut the mugen parts down because the AUDM cat is longer then JDM and does anyone know the gains or anything about the full mugen system in the Ek4?

i guess downfalls would be scraping them depending on how low your car is, but its only 7mm

[andiiso]

ahhh ok, sorry for asking so much but i done research and havent been able to find out anything, but so far ive found that, i could go either (need some correcting please)

TODA headers (can explain difference between 4-2-1 and 4-1 please? sound, power, gains, mid, top end, low etc), (JDM cat, AUDM cat??? or the TODA cat), mugen catback exhaust (is it twin loop for the b16b .. b16a ?)

OR

mugen headers 4-1 (JDM AUDM cat ???), mugen catback exhaust (again, twin loop?)
this is all for the ek4. any opinions etc and corerctions please ?

[TheSaint]

also want the same info as andiiso but for dc2... please help us

[0098]

4-2-1 is better for midrange 4-1 for top end.
Jdm cat or Audm i guess would pretty much be the same and restrictive, i think there could be a difference in size also.
The cat Toda can supply is High Flow.

[andiiso]

i know for a fact that the AUDM dc2 cat is longer and JDM dc2 cat is smaller and if use JDM cat it will fit the mugen parts onto it perfectly widout any cuttin etc. but i think i know what i will put in, i probably go for the Toda 4-1 and the TODA cat and mugen catback etc, even though my car is not gonna be that low im still scared of the extra 7mm lower on the mugen headers, somethin just mite go wrong, anyway, thanks a lot people, btw im andii and i just recently bought a 95 ek Vtir nice to meet u all and thanks again for the help

You will need a new cat, the donut flange is larger on JDM exhaust manifolds.
Also cat length is different.
TODA headers are 4~2~1, ground clearence is not an issue.
If your EK4 is stock, you can expect same gains as previous dyno sheet.

ic, i saw before someone posted that 4-2-1 is more midranged without loss in the top end, and 4-1 is the top end gain, and i have always thought mugen was already mid ranged so was hoping for a combo that gives me a gain in the full rev range and not just top end or mid ranged, but more evenly spread etc. any opinions ? or corrections ? (btw sorry for being noob but i researched alot on buying a eg vti or si for conversion but ended up gettin a ek4 and havent done any previous research watsoever on it so im noob with the things on this car and ive been reading up as much as possible on it already)

If you get the right 4-2-1 u will gain all throughout the whole rev range!

[andiiso]

but in saying the "right 4-2-1" i gone blank, what is the "right" one and what is the "wrong" one ... so far ive read up, xforce is bang for buck, toda is awesome and mugen spoon are fairly decent, and according to my friend who drove the dc5, he had xforce headers spoon N1 exhaust system etc, he was going for full top end power, so xforce is top end bang for buck im guessin, but thats for dc5. so yerr .. if anyone got any opinions on which system combo etc would give me a good full rev range gain on a '95 ek4 (b16a2) please post opinions .. thx heaps once again

[Benson]

The ones that Dave made for us, made power throughout the whole rev range... we gain 5kw midrange and 10kw top end. So it really depends on the design of the 4-2-1.
