Best N/A Header + Single Exhaust Setup

[STAiN MASTER]

G'day guys,

I want too find out whats the best header + single exhaust setup for the S2000?

I have searched on s2ki I know some in mind but cant find any hard proof i.e dyno results that prove their thoughts.

So if anyone knows any info please share :)

I cant remember the website i was on but i saved the dyno picture but sus out the ARK N2 Exhaust + headers i've attatched the dyno pictures of it..

[F20C]

invidia headers without the exhausts though.. might be helpful =\

[vyets]

J's racing header - Proven many times to be the best gaining header. That shouldn't be too hard to find on s2ki.
Any most 70MM exhaust will give you good gains. If you want maximum power go for the Amuse R1000, T1R 70RT, J's 70RR. Straight through titanium design exhaust for maximum gain & minimum weight.

If you want 70MM but still retain the cat, there are alot more choices ASM 70T, J's 70RS.

If you want 70MM but don't want to spend money on titanium and still keep the cat. ASM 70SS Which is still very expensive, t1r 70EM Or the Greddy TI-C (bang for buck)

[STAiN MASTER]

thanks for the links guys, so from what I gather is that with a J's header with cat or hi-flow cat with a 70mm single is the best setup

which out the single exhaust is the best?

[vyets]

No the best gains are with the J's header + straight through 70mm lol no cat.

Most of the single exhaust perform very similar there hasn't been one that has come out on top yet unlike the J's racing header.
It's really upto you weather you like the sound of a titanium exhaust or a SS exhaust. Or if you like Loud or quiet.

The quiet ones will be the ASM 70Ti and 70SS. Also the t1r 70EM. And the loudest would be the R1000.

[ChromZ]

also note, the T1R 70R v3 has the provision to be a catback also. the package comes with a test pipe if you wish to go the extra step.

being loud at the track is good, on the street.. depends how much attention you like.. saying this from personal experience ;)

I agree with vyets and ChromZ. You may try your luck, but just remember Stain, that your car is not legal without a cat. What are your goals with these mods - outright power? I found the biggest benefit were the weight savings.

[STAiN MASTER]

^^^ Just inquiring, I want too know what will be the max hp setup with a hi-flow cat, I wouldn't run a test pipe.

I might change my current setup.

[Djbinh]

has anyone got the tri-y headers on there s2k

[aozora]

What vyetz said :)

Toda headers also shows similar gains apparently if you want another option.

It's difficult to get power N/A with simple mods. Maximum HP with intake, exhaust, header and tune is about 210-230whp on a Dynodynamics dyno.

I think your HP numbers are abit high unless the dyno I was the on was punching out low numbers, I know its hard to yeild power from an N/A, with my setup I got 138kw @ the wheels, stock was 130kw

Mugen header
Hi-flow cat
Invidia Dual V3
K&N FIPK
ECU tune

The car feels much stronger then before but I think with a single exhaust setup would of been better.. Comparing with my before and after, the mid range is alot better with the mugen header and hi-flow cat with vtec coming on at 4,000rpms I dont have that power dip like before when vtec came on when it was stock.

[F20C]

Well if you end up changing to a single wanna sell me you dual v3? lol

[ludecrs]

For interests sake, I think I pulled 195hp with the Toda headers K&N FIPK and Invidia exhaust.

Why are you running vtec engagement so low?

Do you still run the OEM cams?

Ah... are you suggesting your setup is the best possible for max HP? ;)

[jooboo]

while on the topic of exhausts, what would be the quietest 70mm dual or even a 60-63mm...anyone have the 63s sparrow?

[ludecrs]

I thought the HKS Hi Power?

One for sale in the classifeds for $800 atm.

Will keep you in mind ;)

Could of been the dyno i was on was doin low numbers, this is the thing I can feel the difference in power from when it was stock.

Still on OEM cams, with the hi-flow cat it can handle it, so ive been told

I don't think its the 'best' setup, trying too find out what is, but cost does come into the equation aswell how much are you willing too spend for those extra 1-2 hp

isnt anything below 5k on oem cams to agressive and reduces the life span of your cams?

[mikoZ]

yes, that one of the reason y we need sum good design aftermartet cams.

[STAiN MASTER]

^^^well if me cams go, good excuse too get some TODA ones :D

lol, everytime i wanna buy sumthing, I always find myself sum excuse ...

[ludecrs]

I could feel the difference when I installed the Toda header. 5-12rwhp difference across the entire rev range according to the dyno printout.




Still on OEM cams, with the hi-flow cat it can handle it, so ive been told

Reason I asked was not because of the hi flow cat, but because the OEM cams are primarily designed for OEM use - approximately 6000rpms before the crossover.

I had mine set at 3600 or there abouts on the AEM with the S/c. Huge fail. Re-set it back to 6000 (as I still run OEM cams) and I picked up an extra 20HP (along with cleaning up the AF/R's along the way), as well as a much bigger 'kick' in engagement, whereas set at under 4000rpm, there was no 'kick' just a whole lot of noise.

Have to remember, OEM cams, are made for OEM settings - or there abouts atleast.



isnt anything below 5k on oem cams to agressive and reduces the life span of your cams?

I'm of the believe with OEM cams, you really shouldn't be setting your crossover point below 5000rpm. Again, just my theory, and I'm sure someone more knowledgable in this area, such as Adrian @ Toda could chime in to prove for or against.

[F20C]

there was no 'kick' just a whole lot of noise.
.

lol =P

[STAiN MASTER]

Ludecrs: I know what your saying when you mean "there's a whole lot of noise" this is what I get now, I dont get that kick that you normally get at 6,000, I get a slight kick at 4,000 then at 6,000 it fully comes on but there is no surge of power like before at 6,000 when vtec kicks in. by the way adrian tuned it :) Im happy how its turned out, my mid range has incredibly alot more hp and just abit more on the top end then before.

[ludecrs]

^

Thats exactly what I had too, but when I set it back to 6000 and cleaned the AF/R's up I scored the 'kick' back, and an extra 20Hp to boot right through to redline, on the same boost pressure as before (I know I'm talking FI, and this is N/A but the theory is the same).

I should mention Adrian's tuning my car shortly. I'm really looking forward to it actually.

Oh awesome, Adrians good he takes his time and does it properly, when will you be going? so that means your coming too syd yeah?

[F20C]

hey stain, your invidia exhaust.. did you get it imported or is there somewhere in aus that actually sells them cheaper lol?

[ludecrs]

Nope :p He's coming to QLD for a week starting next week.

you got the headers in already? yeah man take me for a shpin, what about the ecu?

[F20C]

stain evasive is down.. how much did you pay? i know the aussie dollar is worth abit more now so it could possibly be cheaper..
