obx race headers?

[lemonhead228]

I heard a lot of bad reviews of the company itself but has anyone ever experience wit these before?
Any help is greatly appreciated.

[MugenReplica]

The company makes copies of already established products. When it comes to standard bolt ons most of you guys on here think you need an expensive header because alot of $$$$ in the import world seems to mean that a product is of high quality, but that isn't always true. If you're just buying a CAI, exhaust, or header you'd be stupid to dump $$$$ on one of those if you are only DDing your Ep. My suggestion, if you're not going for a show car or a HUGE whp engine build, the OBX bolt ons will be as good as anything you can buy for the price.

I've had 3 race headers since I've owned my Ep3. First an RSX-S first gen DCRH, then a RSX-S Buddy Club header, and finally a OBX gen 2 RH (stainless copy of the Comptech RH). The OBX has been the longest lived and most reliable of those three. The ceramic coated DCRH rusted out AFTER the flex pipe cracked. The Buddy Club RH just fell apart one spring at a time, not to mention the stainless was of shotty quality (just like the OBX, but the OBX was 1/3rd the cost). The OBX Gen 2 RH has faithfully served me through the last couple of years problem free. It's honestly up to you, but alot of the money conscious guys are going to say the same thing.

If you are going to buy OBX ITB's, LSD, or anything with many moving components however, be advised you'll have to rebuild or fix them before you install them. They have no quality control, so the OBX items with moving parts often times need to be fixed or upgraded.

Excuse any rambling as I have insomnia at the moment, but thought I'd try to help answer questions on the forums.

[lemonhead228]

Thanks for the reply. I was doing research and by your experience it seems like these headers are the best bang for the buck. I was just curious cuz obx review on the company itself have fitment issues. Can't wait till it comes in.

[MIGEEZY]

I'd go with the KiddRACING/Private Label/CRSX header, it's the best bang for the buck IMHO! That's the header I'm getting down the road.

[cronicEP]

He's looking at a $300 ebay RH that is a decent build for what it is. He wasn't asking for your opinion on what brand of header he should get, hopefully those headers work out for you. I personally think that the obx v2 is a great product IMHO! LOL. Why would you spend 600- 700 bucks on a header that puts out 2-3 more WHP?

[lemonhead228]

Yea I'm buying the headers used. It bolted on his a3 and did a k24 swap and still ran it. He heat wrapped it. What's the point of that?

[Rictorious88]

If he heat wrapped them it was to prevent a ton of heat in the engine bay and to keep the intake from getting heat soak (assuming he is not using a cai).
BTW wrapping your header can lead to cracking, i wouldn't do it.

[jonathan13]

Please stay away from OBX. I have experienced bad things in the past with their quality and fitment. If you can't afford a nicer header just wait and save up a little and you will be very happy you did! :) Oh also keep in mind that if you do get a race header it is a good idea to upgrade your mounts or at least do mount inserts- This prevents any premature cracking or broken welds

[kale's blue ep3]

do they obx rh rust?

[k20power]

I think I heard that obx is better than the dc RH

[jonathan13]

I don't know of any rust issues with obx but that could be possible.. the issue obx has is with their quality.. they break very easily and seem to be cheaply made. I don't think that DC has the best products either but IMO the craftsmanship of DC is much better than OBX

Tell me the differences between the DCRH and the OBX RH? PLEASE

When I had the obx header I had no problems for a couple years. No rust issues, cracking or flexing issues, the finish held up also, just needed a clean after 2 years. In fact a fellow user is now in possesion of my old obx header and he still loves it. The only reason I swapped over to a new RH is because of k24 fitment. For the price you CANNOT beat OBX bolt on products. HANDS DOWN, if you daily your car and want a RH...obx is the way to go...Don't question me! LOL

[AKEP]

from the headers i was looking at, the DC (ceramic) was like the only one made of mild steel, which is why they didn't want you to wrap it. whether it rusts or not IDK, but all the other headers are made of stainless, which is alot more resistant to rust.

yes

[T_Virus]

My OBX RH vers 2 is still looking good and has not rust. Fitment was really good too.

[kale's blue ep3]

well a obx rh fit with a megan midpipe?

[kmbkk]

I just did a K24 swap in my EP and used the OBX RH. Fitment was fine and build quality seemed good as well.

[cronicEP]

well a obx rh fit with a megan midpipe?

yes

[kale's blue ep3]

no modifications?

[cronicEP]

no modifications?

Yes no modifications. the only thing is the megan midpipe is well known for it's hit or miss on fitment. Either it fits no issues, or it hits the undercarriage when correctly fitted.

[thakid]

Obx is crap. Dcrh is better. But if its just a dd and less then 220hp. Then obx rh will be fine. I been doing research on this topic lately because I too am gettin a race header soon and decided to save up and go with ssr. Some say why spend 3 times more on it when it only gives 2-3 extra hp. Its not only 2-3. Its 10-20. And some say why not buy a dcrh then spend the money you save on other parts. Well for 1 you won't be able to buy anything else to give you that much hp. If your going to do a build why not do it right the first time.

What kind of motor are you getting 10-20 hp over an OBX or ClubRSX (which is a copy of the SSR)

[Deadphishy]

To they guys running an OBX with a K24, I'm due to replace the giant exhaust leak i have in my crappy DCRH. what verson OBX are you running that clears with the k24. I got married and all my money went bye bye. So what ever doesn't leak is good by me.

[thakid]

I'm not saying you can slap these ssr header onto a stock engine and it kill the other headers by 10-20. You'll have to have other factors. Intake, I'm, kpro ect.

[Passenger]

do they obx rh rust?

No not at all. I've had mine for close to 3 years and it has no rust at all

Nah, dcrh is cheaply made. Its common knowledge that the flex pipe breaks and the header itself rusts. The people who are making these claims that the dcrh is better than obx are the ones who have never owned the obx.

*edit* like Mugenrep said, I wouldn't go so far as to buy "moving" stuff that obx makes but their bolt ons are made well. They're replicas of other brands so if you think the DCRH is better than (lets say) obx rh version2 then you think (for God knows what reason) that the DCRH is better than old Comptech raceheader.

[thakid]

This is a crazy topic then. Everywhere I read obx isn't even close to dc.

[Passenger]

This is a crazy topic then. Everywhere I read obx isn't even close to dc.

well like I said with lsds and all that stuff I wouldn't touch it. I'd go name brand and spend the cash with cams and stuff but with bolt ons they're perfectly fine and are made with great quality

[thakid]

Fudge it. These people can buy whatever they want. I'm going ssr. Haha I can care less. Good convo with you guys on this.

[EPSU3]

I'd say OBX because it doesn't make sense to spend over $400 on a bolt on for a car that is only worth $5 grand. Just my negative point of view though.

[lemonhead228]

i just installed the headers! man did i ran into alot of problems..

well the fitment was perfect!! i love the lil deeper toon it has and the mid-top end it gives me(:

next up is a megan mid-pipe with the clubep3 resonator and apexi ws2 axle back!!

Not really problems but the stock stuff was a bitch to take off.

and had loosen the front sway and tilt the car on one side to cram in.

But once I got it in place it was good to go

Obx race headers(: when I got it used, they barely used it and it was heat wrapped already.

Yea I pre-sprayed everything wit pb blast so most of the nuts and bolts went off like butter.

[lemonhead228]

I have a question.. after I put on my race headers. My check engine light came on and got it checked at autozone and the code that POP was the o2 and cat.

Why is it popping that code?

[T_Virus]

because you need a 02 sim to trick the ecu as you no longer have a cat.

im trying to buy them but they charging me CA sales tax! I HATE CA!

[T_Virus]

It maybe the same style depending on which version you getting, vers 1, 2 or 3, but different fitment when using mid pipe and exhaust. Either go with EP3 fitment or you will have to work with the DC5 RH, DC5 midpipe, EP3 Exhaust.

[T_Virus]

Yeah, we're stuck with this.

The one I quoted is *I believe* version 2, but its the comptech replica. If you're asking if the Ep3 version being the same as the DC5S then yeah pretty much, I do believe the DC5 might be slightly bigger (as far as the primaries) but thats just hear say as far as Im concerned.

[spartan]

oh yeah forgot about the damn mid pipe.
What are you rocking?
i really don't want to trust megan but if it doesn't really matter i'll do it.

[spartan]

got the header today. looks sick!
welds look ok.

i see that the 02 sim is no longer for sale and kpro can clear up the check engine light but what do i plug those holes up with?

[T_Virus]

primary and secondary sensors?

[Type_R_Nammer]

I'm planning to pick up this header myself also.

Do I need any additional hardware for installation?

And also where can I find an o2 simulator?

If you guys can post a few links it would be great appreciated!

[sidious141]

I installed mine earlier this week and was generally pleased with it.

-Exhaust tone sounds a little different in a good way. Not ricy at all, a little quieter than when I had a test pipe
-Fit like a condom
-Butt dyno was pleased
-Noticeable rattle now and then, I think it may be one of the sensors rubbing the exhaust heat shield underneath the car. I’ll be fixing this tomorrow weather permitting


The box mine came in said it was for a DC5S. In parenthesis, it said "short pipe" underneath that.

I ordered mine from racingpartsdepot on ebay with no problems. They were quick to ship and to respond to an email I sent.

Which version did you get? Also what were your dyno #s?

[sidious141]

V.2

No dyno, sorry guys. It made a noticeable gain over stock manifold and test pipe.

[japanracah!]

i think i'm going the obx rh route but don't know what midpipe to use. I guess megan? if anyones runs megan on obx rh let me know if there's issues. and what other midpipe choices fit well with it.

Hey dude just put on the rh on yesterday, feels great!
Used greddy spectrum elite axle back an midpipe.
only problem is that part where the little test pipe butts up against the mid pipe it only 1.8 inches.
That's kinda retarded, and where the springs an bolts go together there is a loud noticeable clunking during idle .

OBX vs stock? i have an opportunity to do a straight up trade for stock.. worth it or just keep stock?

I had to do this with my DCRH also. The only reason I can think of for it is because it makes the flange stronger...

I have K-pro but not installed and never had a chance to get it dynoed. You should do it.

[Twisted-X]

How long did it take you, an how much did you do?

Maybe a half hour of dicking around with a dremel with a side-cutting bit. I went down to about 1/16 of an inch away from the inside of the pipe. No problems with leaks so far.

awesome, im gonna give it a street tune with kpro then.
I really don't think dyno is worth it.
I wanna take that little test pipe out an dremel it but its a bitch to take off an a fat bitch to put back on.

[T_Virus]

oh your K24? Well, I just sold my race header to J000stin last night and he has a k24a2 so hopefully he doesn't run into troubles and he took off his front sway bar. I think the noise you are hearing is probably because of your front sway bar. On my k20a3, I didn't need to remove or adjust my front sway bar.

Shit. I have itr front sway. probably have to get used to the noise then huh.
What if i heat wrapped them, you think that could help?
No im not k24, but im planning on it.
I think cuz it sits higher there will be a real problem with the sway bar.

[T_Virus]

Take off the itr front sway bar and use your stock. You really don't need that itr front sway bar as it doesn't do much of a difference than the rear sway bar. Also I never did heat wrap anything before but I have heard bad stories about them.

[j0000stin]

went to tracy from sac today (1hr drive) to install the header. got the header off only to find the studs to the cat are rusted and stripped as fack. then when i put the header on i realize T-virus didnt give me the adapter piece for the donut gasket.

ran open header all the way back to sacramento (thank god there were no cops on the freeway) got the header on and my secondary o2 wont come off. started it anyways and no leaks and everythings good except from the exhaust leak from the missing o2. i'm going to get a tool to get the 02 off and i'll tell you how it feels

[T_Virus]

Sorry man, I forgot all about the adapter piece. lol...But man open header? was it really really loud? Well, your almost done getting it on anyways. Whatever you do, becareful with the 02 sensors. Don't drop them, don't let anything touch the tip or your be looking for a new 02 sensor. That's what happen to me.

I was thinking of just wrapping near the sway and the oil pan.

i've used heat wrap before and havent had any problems. but i used to spray paint vht on beforehand. there has been instances of people's headers cracking because the heat wrap holds the heat in which causes the header to crack over time?

I'm not down to remove my sway bar. I'm going to heat wrap part of the header around the sway bar and hopefully it will help.
It looks like i really wont be able to use this header when i get my k24 with out problems with the sway, but hay maybe wrapping it might help with the k24 too!
Does anyone make a header that's made for a 2.4 swap for the ep or dc5?
I know skunk2 makes a special header for k swapped EG, DA, EK, DC2 chassis.

What about us?

Getting mine installed on 2nd of May. What diameter did you use on your midpipe to see a "noticeable" gain?

I can't tell you the diameter of the midpipe off the top of my head but I have been running a Greddy Ti-C catback for the past few years.





As a note on the earlier mentioned occasional rattle I would experience, it has been fixed:

-The primary o2 bung was pointed more upwards than most pictures I have seen posted by members that are running an OBXRH V.2. I had to cut a small piece of the heat shield out which eliminated part of the rattle problem.

-Installing this header moved my midpipe closer to the car to where it was barely kissing part of the edge of the frame. A couple of loving whacks with a hammer to where the midpipe was touching solved this problem eliminating any rattling issues.

The problem with the midpipe touching the car may have been unique to my header(such as the primary O2 sensor placement screw up) or it may be that my catback/header combo drew it too close to the frame.

Either way, for what the header cost....I'm not crying about it.

Wow, you had to do some modifications to make it work. But good thing you knew what you were doing. Mine was a good fitment, had no issues.

[303EP]

I've had mine in for about 3 weeks now, no issues at all, cleared the sway bar fine, it is pretty close but I have ESMM's so it probably doesn't hit because of those

[lemonhead228]

Hey all, I ran these headers for about 5 months already and it still good.

When i got it, it was already heat wrap also. It was noticeable whenever I open the hood, it wasn't as hot as before.

As well I bought these from a guy that did a k24a2 swap and he ran these headers.

I still needa get that o2 slim. Been lazy lol

[ep3jd]

I've had mine for like 3 years, I enjoy it. One day I'll wrap it

[sidious141]

It really was not as bad as it sounds, but still an inconvenience.

I have not seen anyone else with the same fitment issues.

[T_Virus]

Yeah i think you are the only one. The other issue from other people is that it is hitting their stock front sway bar but mine clear completely on the stock front sway bar.

[lemonhead228]

Would an 05 type s midpipe fit wit my obx headers?

[Type_R_Nammer]

After doing my emissions check, I'm strongly considering the obx race header.

Quick question for you guys, what kind of defoulers are you guys using and where did you get it from?

Let me know thanks!

[getfreshcrue]

You guys should Check out this race header you could get a good deal from him a little more expensive than the obx but better quality lemme know what you think

can you run a RH without k-pro? any downsides doing this?

[poeticfinesse21]

can you run a RH without k-pro? any downsides doing this?

Your car will run lean and you won't reap all the benefits of the RH. Get a reflash or get k-pro.

Sorry to bring a dead thread but is there only one version of the obx header the V2? They dont make the version one no more? Im in a process of doing a k24a2 swap would this header be a good setup?

[gtimportfanatic]

the OBX is good but i would advise finding like a PLM header or Kidd racing which is the same just different reference. these are RSX based headers, you will find em on club RSX, and to run these you would need to run a Type S kind of midpipe with an EP3 axleback ..

Thanks. Im planning on doing the megan midpipe with the stock ep axelback also. So what is the real difference with the obx and plm anyways? Besides $200 more? If itw only 1-2 hp then the obx is bung for the buck.

[Her-Name's-Ally]

what most people would say and just my experience seeing a good RH and a not so good RH is the quality and longevity. I cant say anything for the obx but I have a DCRH and my buddy has a BCRH and boy what a difference. Hope this helps in any way.

Men now im stock either the plm or obx. If the obx last for 2-4 years then i guess im ok with the obx then.

[Her-Name's-Ally]

its up to you. I mean you know the better quality is from everyones response its just up to you if the extra 200 is worth it in your opinion

Ill just save up the extra cash then for the plm. new obx v2 rh is 270 shipped from most place where the plm rh is $415 pickup from south SF. So its only $135 difference.

[Her-Name's-Ally]

i know phil is selling one for 400 shipped. hit him up maybe he will hook you up with a deal

[klik]

I wonder if the megan midpipe will bolt up to the PLM header? I know the obx will because a couple of member had that set up before?

[gtimportfanatic]

if the megan midpipe is for a Type S then yes, as long as you get the test pipe with the header too.. so when u buy the header it goes to a 2 bolt flange, then there is a 12" or so test pipe that gives the 3 bolt pattern for the midpipe, since most of the plm headers are RSX specific the midpipe needs to be RSX S specific and you would run an ep3 spec C section(axleback) .. pretty simple shizzz my man

Thanks. Im still leaning towards the obx rh as of now since i have the stock axelback and i will just need a megan midpipe then. Budget is still a factor here and the obx seems like having a good review from all over the place.

[lemonhead228]

I made this thread 2 years ago and my header is still fine. Really good material. I drive a lot since I have to commute to school and work 5 days a week. I put about 30k on it already and still no problem. The guy I got it from had it on his k24 ep also that's the reason why I got it.

I was planning on gettin the Megan mid pipe too but never had a chance. I have the 06 dc5-s mid pipe and want to use it so bad but I haven't came across a cheap rh for it yet to put on lol

[hondakiller]

I bought an obx header won't fit around my sway bar! Not very pleased

[Her-Name's-Ally]

[Type_R_Nammer]

Any reputable sites on where I can buy an obx race header?

[SkareKrow]

Running a DC5-S Spec OBX V1 RH for almost 5K no problems yet. Significant difference then stock with an Apexi N1 Midpipe but no axleback. Im untuned but losing a lot of power due to no axleback. When I had the Apexi N1 Axleback before it broke due to being low what a difference. Was pulling great.
Here is a vid of it. Just OBX Version Type S Spec Race header with no midpipe.

Im very satisfied with the results. If I had to upgrade would either be to a BuddyClub or Toda!

Are you sure they are both stainless steel?
Are they both ep3 specific?

And I think there is a thread showing the adapter flange needing to be bored out but I can't find it, so... it's a good idea to bore out this flange from 1.8 to 2.5 inches. I haven't done this but I need to. Hope this helps someone...

*This needs to be done for the OBX V@ RH EP3 spec.
The Type-S spec adapter is 2.25"(matching the Type-S midpipe).

[Dreadknotz1025]

I don't mean to repeat what you've posted above, but your saying that the OBX S.S. Headers 02-05 Honda Civic Si (http://www.sparktecmotorsports.com/h11087bs.html) needs to be modified before installation? ( It will not bolt up stock, requires modification to fit)

1) Does the headers fit/bolt up with the 1.8" "bottle neck" OR your doing this to maintain 2.5" throughout exhaust?

2) How did you "bore out" the flange? Was this done at a metal shop?

[Eddie Murphy]

Hey dreadknotz, They bolt right up out of the box. You would want to have the flange adapter bored out to 2.5 at a machine shop, unless your comfortable doing it on your own with proper tools. It will eliminate the restricion that the small 1.8 opening causes UNLESS you plan to keep your stock midpipe.
