Talking NYAHO (Need yet another header opinon)

Hey guys,
Well I have been trying to keep up to date on all the headers out for the ej25 and well I finally decided that I should open my wallet and put the money on the table. What consirns me though is noise, I am an old man (actually 19 heehee) and I don't like to have an annoyingly loud exaust or somthing that gives way to much attention. I wouldn't mind a nice boxer sound, but I don't want something that drowns out my bumpin tunes when crusing at 30(stop and go city) or 50(leaving city) or 80(going to class)

I am also planning on putting a supercharger on my car (2 weeks) and I want something that will help flow, and from what I have read... any n/a header will do fine. I am looking for somthing with good n/a power and not overly loud but has a nice sexy boxer growl to it
From what I have read it seems to be either Borla or MRT.
What ever header I get, I will need to also get a highflow cat or I will only use these headers "offroad"

What are you opinions?

-Neal

my TWE headers look really nice. Ceramic coated, smooth flowing. However, i'm still waiting on their cat to come in.

DoctorNick - most important thing in deciding which header to get is where do you want the most power.

The iON/Brullen header-system or header-back system will lift the whole power curve up vertically. Pros about this set-up is it'll flow lots (if you couple it with their 2.5" cat-back section), made of 16gauge T304SS, carrys a ltd lifetime warranty, as well as being able to choose your own acoustic preferences + looks.

The TWE stuff, is ment for more use with their cams, which accentuate the mid-higher rpms.

The MRT stuff is cheap, however you get what you pay for. Just look at how many cat failures there've been.

Borla you shouldn't even consider other then a sound mod.

Nick, what supercharger have you been looking at for your 02 RS ? I'm always interested to see what the other 4EAT boys are up to

luckily... i have cams.

In any case, the reason why I went with TWE:

1) longest 4-1 header that I can see. What does this mean? like GTBguy said.. 4-1 give you mid-topend. which is what our cars severly lack. If anything, I dont think it hurts lowend, it just doesn't boost it. At least, with Honda tuning this is true. (they have both 4-2-1 headers, and 4-1 headers)
2) Ceramic coating.. always nice
3) True Equal length. Important in N/A motors.
4) Stock cat hook-up point.. juuuuust in case I go turbo. =P

Don

i'm still waiting for their hi-flo cat, but I went with a TWE header + hi-flo cat, and a Brullen 2.25" dual tip QUIET cat-back. The brullen catback sure does look puuuurdy.

Hmm, Can I just get the headers and nothing else? I have a custom cat-midpipe-muffler right now and I don't wanna buy another exaust when I would just need to sell it off because I am going my custom way. I also want to use another exaust that will be for a no cat race pipe.

k, a little off topic:
DrBoy01
I am hoping to talk my friend into replicating my supercharger setup and selling it. Right now it consists of a eaton m62

its so prudy

back to topic:
Why is there so much negitivity to borla? is noone realy getting any power out of them?

thanks for all the info.

DoctorNick - yes you can purchase the header-system alone, however you'll have to get your mid-pipe modified to fit the hi-flow cat's exit.

So they ceramic coated them afterall? Last time I saw them, they were only painted in Hightemp paint.

they sound nice, but the gains are modest compared to other headers on the market...this is probably mostly due to the fact that they're made to be a direct OEM replacement (i.e. mates up to all the stock stuff), and don't come with a hi-flow cat section.

i just installed a set on my car, and other than lovely sound, getting rid of the rattling heat shields, and smoothing out the power delivery (which was greatly appreciated), they really didn't offer a huge gain, 5-8hp max. i'm sure a better flowing cat section such as the random tech would help quite a bit, but in the meantime, i'm happy to not get whiplash from taking my foot off the gas in 1st and 2nd.

DoctorNick, noise will be handled by your muffler/resonator... don't worry about it. Ask yourself what you want out of the header, every response seems spot-on (except for the crack about the MRTs being cheap). I went custom (pipe cut/bent/welded locally) due to cost, it ended up cheaper than anything on the market... sure its not the "best" one out there but its better than stock (and Borla ).

Hey Neal,


Tim Sanderson and I just installed some borla headers on my car this past weekend. They really smoothed out the power delivery and I notice that it has improved mid and high range acceleration. As others will tell you, they sound AWESOME. I already had the borla catback and they compliment each other very well. I don't even know if I want a scoobysport muffler any more (Unless I go turbo). Last, and certainly not least, they are at a great price ($308+sh) and come with 1mil/mi warranty. I got mine from SPO motorsports and they were pleasant to deal with.


Mick

Edit: I forgot another good point for the borla headers: No CEL issues.

I would vouch for SYMS headers. Granted you will have to give up your organs to pay for them, they are worth it. Great build quality. Sound is nice. Nice and deep, but once you step on the gas, car awakes.

I have more issues with my muffler, so I am playing with that. I believe getting a Japanese muffler will make it sound raspier at the topend.

Performance wise. The powerband is smoothed out. Top end pulls harder and throttle response is nice. Wish I had numbers to give you, but that is all I got.


Going to reset the ECU and see if I can get more out of the car.

windfactory - our header system was actually modelled after the SYMS EJ25 N/A header. Only difference is that ours has a hi-flow cat, and ends @ the stock mid-pipe/cat location. Hence power throughout the rpms is lifted.

i traded with a fellow member, Section 8.

I have no idea where to get one, but I know it is not cheap. Alll I can say is that the headers are much lighter than the stocks and look great. It is longer than the stock headers , so you will have to get your cat-back modifided to fit. Cost me 25 bucks to get my Greddy cat-back to fit.

I think you can try SPO motorsports. They might be able to help you get in touch with someone who can get you one.

iON Performance Inc - Thanks for your kindly info and reply. Now i have yours in my research info. the only one thing i dont want is the cat comes with header.

Teamugi - I can get one from my friend who lives in japan but the only one thing is the cost too high. i just wanna check out if u were getting yours from a lower cost vendor...

I'm now kinda getting all info together for building up my RS right the way.... thanks guys for sharing.

Teamgui: Actually that is a SYMS Legacy header...which is why you need the custom header-back setup. I know cause I helped him swap it out the other weekend.


Danzborin: I stand corrected...I now have a CEL.
