Called up importpowerhouse today and asked a few questions about the RMF narrow,
im soon to swap a jdm itr swap into my 98 ek. purchased it w/o an exhaust manifold.. after doing alot of reading on here, i grew to find out that its not worth buying a dc sports header, or really any under 500 bucks. so ill just bite it and spend the 700 for the dtr narrow. and reak the benefits of hp and torque. the few questions i have are:
Are there any clearence issues? ( i will be running ac, powersteering, and a fluidine radiator.) let me know a few things about this manifold and what you guys think of it for the money. also when i do this swap> ill be using a apexi world sport exhaust that was on a ls swapped ek hatch w/ dc header 4-2-1. how much welding/ fitment do you think i will have to make to make this manifold work with this. the exhaust has a cat pipe welded/ cut to fit that swap. and im planning on gutting it and maybe just add or subtract pipe... dont know how much longer this manifold will make it. lemme know-

i think you are alittle confused

Importpowerhouse = RMF

 

Aww man, you never heard of the DTR Narrow header??

nope but i heard about the RMF b-unit header though

 

for 795 bux stainless steel



There are brand x headers all over the place that claim dyno proven this and dyno proven that. well

"Well all that basically doesn’t matter at this point because the Hytech layed down the biggest peak hp and torque numbers of the day with 196 hp and 135 torque and the area under the curve didn’t seem to bad at all either. No fitment issues at all with this header and and quality was definitely among the best on hand."

titan motor sports

"Peak power production rose from 160.4hp to 168.5hp"

TPR

"RPM +Torque +HP
--------------------------------------

2200 21.53 13.49
3400 22.87 14.86
4500 21 ? 21.15
5500 23.59 29.41
6000 20.77 23.72
6300 34.33 41.03

[edit] This his hard to read. The numbers represent the increase in torque/hp over the stock exhaust[edit]"

club 3ag

theres a bunch else out there - keep that in mind

 

sorry i meant to put rmf narrow. ive been looking at the dtr and hytech header also but dont wanna spend the bank for all that

 

I can only say that if your going to get any header you should really consider spending the extra on stainless steel. And in the higher end header range there's really nothing between DC sports and this in price thats worth mentioning. I got alot of flack from one of my friends since I can get the hytech "copy" for 1/2 of this. But once I took it over to his shop and he had a look at it even he had to agree that even beyond "actual" results this header was built very meticulously and to last, everywhere you look on it it's evident and even the production header caries a patent number for design.

 

hate to inform you like this but check out the bseries shootout RMF &gt; *

 

yeah that was a good thread /\

oh this should be good

post that link and lets compare.

 

Hytech production header = made in China or Taiwan or something

RMF = made in the USA by a TRUE CRAFTSMAN

so to the guy above that was talking about the great quality of the Hytech production header, well, maybe you've never seen an RMF header. I know when I saw one the first time my jaw DROPPED

So I think that if you can afford the RMF you should get one FOR SURE. They are also PROVEN time and again to make power. ****, ask my buddy Chris at Hookups - he has a drag header made by RMF like 5 YEARS AGO and he said it was the best header he's ever tested. and just think, obviously RMF has advanced and perfected his designs even more since then.

Also RMF headers ARE available in stainless if you ask for it. I do agree with the other guy that stainless headers are definitely worth the extra cost.

If a stainless RMF header is out of your price range, the Hytech production header/Rage header (same exact header, made by same overseas factory) will definitely make you happy - it's a good design and makes awesome power. But like I said I think that if you can afford it, the RMF would be the way to go. Plus you are supporting an INNOVATOR that makes valuable contributions to advancing our sport/hobby/whatever you wanna call it.

I feel the same way about SMSP and DTR (now SSR), both make awesome headers.

I will never again buy anything from Hytech because when I worked at a shop I had to get headers from them for several customer's cars (at the customer's request) and he has HORRIBLE customer service (and incredibly long lag times for custom headers...). Just my opinion though, take it for what it's worth to you - if I wanted that header I'd get the Rage one from KTeller, I have bought from KTeller in the past and he has AWESOME customer service. To me the service I receive is a crucial factor in deciding whether I will go back to a company and give them more business.

So their you go, that's my long-*** rant on what header to get lol

made in china for real. i got one sitting here without a hytech stamp on it, dead on that hytech pic, i mean to the T. i think it might be a hytech, without the stamp!

 

Yeah, the Hytech Production Header is made overseas but it is a nice piece.

hahahaha

 

1.your ipod is made in china too would you throw that away ? - no and theres a good reason why not because no matter where it's made to keep costs down ect it was still designed in the good old usa of a by people who put alot of hard work into them. Not that I care because most of you guys are to busy flaunting your taiwan made JDM stuff or Taiwan made Junk2 stuff to think about what your saying anyway.

2. It's funny everyone chimes in about where it's made, I watched him put the finishing touches on it, since this is probably a trade secret I won't say what exactly but there not "off the shelf"

3. I live in so cal I've seen lots of headers and everyones the best, but every test hy-tech enters there #1. Yeah I'm sure in some dark corner of the internet where all the cool people hang out on some obscure set-up they got ranked number 2

4: Unlike those people I took a very impartial role. I don't sell or endorse anybodys stuff. Mentioning any shops oppinions is worthless because there obviuosly going to hype what they sell.

5: BUT even though I know the final hy-tech piece differs a bit than "any" other one even if the finishing touches were not made and it is the same "The Rage-supplied header produced slightly less top-end power than the DTR-Fab, but overall the Rage-supplied piece was the clear winner. It produced more power than the other two headers almost all the way through the RPM range, particularly between 6k and 7k. The DTR header pulled even around 7250, and from then on the two headers were neck and neck until around 8750 when the DTR pulled ahead slightly and held this advantage until shutoff at ~9k." that was from hook-ups test using a v-afc which I know is not the most optimal tuning method

so um hy-tech is teh fakeness the huh, especially since the "production" piece is still 300 less than the "custom piece" and they are judged the clear winner.

6: Randys been making headers for quite along time, I think the first one I bought was like 4 years ago but it wasn't exactly prodcuction quality although it did make good power I have no doubt had hy-tech produced one for that particular application it would have been the same and this time when I called him I got a less than pleasant answer to a custom piece, no answer from DTR, SMSP told me to buy Toda, Bisimoto took 3 weeks to call me back, Lovefab like all the others had no independant dyno to show and no deffinate date of delivery.

I will admit John's attitude before was "tough ****" simply because he was short handed which is why he has another guy there now. It's not because he's not customer orriented but simply because honda headers don't pay the bills.

Now to the people that talk about proven this and proven that, where is it ?

The examples every single one were done by companies or individuals that "don't" carry hy-tech.

And again in regaurds to "innovator" lol the only reason Hy-tech makes a production header is because years ago when they were hands down better they could'nt make enough of them. The design came from one thats long been proven by impartial people not "all of a sudden the best"


Now for a comparison (I know it's not an SS one but everything else appears the same)

1: it's ugly not that it matters but I've got pimpy polished - the ss version I saw was dull almost brushed

2: the hy-tech flanges are far supperior quality

3: the matterial on the hytech seems better, maybe just thicker hard to tell but it would easy to say this make it more durable.

4: Formula one the pinnacle of motor-sports uses stepped headers, the RMF narrow doesn't maybe for a reason?

5: the hytech header has better ground clearance

6: the hytech header has rear moutning bracket, which is important for anything not to mention road racing since without this it places the entire weight of the header on the welds for the flange, which is why AN-R's ect are prone to cracking there, I have some bad first hand experience there actually a header tech we've been using is cracked to **** in 2 places from this

7: the hytech header comes with a proper OEM style moutning which allows additional play with proper sealing

8. the hytech looks like a better design and even if it wasn't the additional length could easily negate the cat even forgoing a test pipe which does lose power over straight piping from an exhaust and adds simplicity and should be lighter



Anyway time will tell, I'm getting a whole bunch of parts in the next few weeks to redo my b16 and then back to the dyno. but this was it's dyno last time with only bolt-ons no cams ect actually this was the second to last one the last one it went to 8550 and made that last bit to 170. Another guy who has his b20vtec was flipping out as it made barely 8hp more. Even shawn immediately asked me what cams I had. lol proof owns

i love it when header threads turns into pissing matches and all of the sudden everyone is an exhaust dynamics theorist....

 

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by Supernatural &raquo;</TD></TR><TR><TD CLASS="quote">i love it when header threads turns into pissing matches and all of the sudden everyone is an exhaust dynamics theorist....</TD></TR></TABLE>

hey whatever...


I might as well throw my 2 cents in here...

how about trying this little number ?

 

okay I'm going to address your post one piece at a time. But first let me say this - you talk about people being biased towards one company but it's very clear that you're a Hytech nutrider. If you read my post I didn't say ANYTHING negative about the Hytech production header - in fact it's an awesome piece. All I said was that if you can afford it, I would buy a header made in America not in China/Taiwan/etc. The O.P. was asking about the RMF, and instead of giving him any info you basically threadjacked him to post an ad for hytech?

BTW your quotes are in italics:

1.your ipod is made in china too would you throw that away ? - no and theres a good reason why not because no matter where it's made to keep costs down ect it was still designed in the good old usa of a by people who put alot of hard work into them.

I'm not talking about the design (which is good), I'm talking about the quality of the production. Which is something you can't tell from the outside - anyone who knows anything about headers knows that a weld may look pretty as hell on the outside but it may look like **** on the inside (where it matters). Now, short of cutting up a perfectly good header (which I'm not rich enough to do), you pretty much just have to trust the skills of the fabricator - and I know I would trust Randy, Danny, or Dave from SMSP much more than some random guy in China who is doing the work 'to keep costs down'

Not that I care because most of you guys are to busy flaunting your taiwan made JDM stuff or Taiwan made Junk2 stuff to think about what your saying anyway.

When you resort to insulting people it usually means you don't have anything important or useful to contribute. Since that is the point of this forum, I think you should try to resist insulting people you don't even know...

4: Unlike those people I took a very impartial role. I don't sell or endorse anybodys stuff. Mentioning any shops oppinions is worthless because there obviuosly going to hype what they sell.

As I said before, you're not impartial at all. All you've done is basically hype up Hytech as 'the best' and diss everything else. In my post I mentioned 3 different fabricators who I think build awesome headers, and even gave respect to Hytech's design skills - I just don't like their customer service.

Oh and the funny thing about you saying 'Mentioning any shops oppinions is worthless because there obviuosly going to hype what they sell' is funny because Hookups does not sell RMF products and never has....

5: BUT even though I know the final hy-tech piece differs a bit than "any" other one even if the finishing touches were not made and it is the same "The Rage-supplied header produced slightly less top-end power than the DTR-Fab, but overall the Rage-supplied piece was the clear winner. It produced more power than the other two headers almost all the way through the RPM range, particularly between 6k and 7k. The DTR header pulled even around 7250, and from then on the two headers were neck and neck until around 8750 when the DTR pulled ahead slightly and held this advantage until shutoff at ~9k." that was from hook-ups test using a v-afc which I know is not the most optimal tuning method

so um hy-tech is teh fakeness the huh, especially since the "production" piece is still 300 less than the "custom piece" and they are judged the clear winner.

dude you just quoted my own post - maybe you didn't notice but I was the one who wrote that. and yeah it was the winner - but then again we didn't test an RMF so who knows, it might or might not be better. but that's not the point. the point, like I said earlier, is that if you can afford it you should buy a header that's made in America by a reputable fabricator. and like I said in my original post - that's just my opinion.

'so um hy-tech is teh fakeness the huh' I don't know where the expletive you got that since I never said it - I think you're having that problem with resorting to insults again. try to avoid that....

I will admit John's attitude before was "tough ****" simply because he was short handed which is why he has another guy there now. It's not because he's not customer orriented but simply because honda headers don't pay the bills.

Despite being so in love with Hytech you just basically gave an argument why NOT to buy from him! So his attitude towards paying customers was "tough ****"? What a GREAT guy to give your hard-earned money to! oh and you also basically implied that since 'honda headers don't pay the bills' he doesn't really care too much about giving good customer service to Honda people. Sounds like exactly the type of company I want to send my money to!

Now to the people that talk about proven this and proven that, where is it ?

The examples every single one were done by companies or individuals that "don't" carry hy-tech.

I don't 'carry' anything - I don't even work in this ****** industry! Now I will admit that VtecKidd sells RMF headers but that's hardly a reason to accuse him of biased testing - you really think he went through all that trouble to test all those headers just to lie about the results? If he wanted to do that he could have easily just tested the RMF against a bunch of junk headers like DC and JDM 4-1. He did that test to share information with people on this board...

3: the matterial on the hytech seems better, maybe just thicker hard to tell but it would easy to say this make it more durable.

8. the hytech looks like a better design

so we should just take your word for it since you're such an expert? please. the matterial (sic) 'seems' better, and the hytech 'looks' like a better design? oh GAWD I'd better just DROP everything and buy a Hytech because of that!

4: Formula one the pinnacle of motor-sports uses stepped headers, the RMF narrow doesn't maybe for a reason?

no point to compare F1 headers to Honda headers - they are going to look completely different because the motors are completely different. unless I missed the part where your Honda revs to 18,000 RPM?

5: the hytech header has better ground clearance

if you seriously think that this is true, you're an idiot. have you ever SEEN an RMF narrow in real life, or are you just GUESSING based on the pictures? because trust me, I've seen both headers (mounted on cars), and you are 100% wrong. if you can provide pictures to prove me wrong I'd be glad to apologize, but I find that unlikely

6: the hytech header has rear moutning bracket

to be fair, I agree with you on this part. BUT any CUSTOM header builder (DTR, RMF, SMSP, etc.) can easily build on a rear bracket to their header when you order it, since they make it from scratch....

 

I don't understand what your trying to do. First ,That header in that pic is a display header. Every header that I have done has a bracket in the back. And I only step a header when it needs it. Also in that SRZ header shoot out the hy tech made like 8hp less than mine and the 4-1 sms.
here is another one
https://honda-tech.com/zerothread?id=1324962
Do you have any dyno sheets where the HyTech made more?
Here is a sneak peak at my newest header for a BEE. And I was totally in disbelief when I dynoed it. This thing is amazing. And we tested it over and over to make sure it wasn't a mistake

 

Randy do you have the link to that SRZ header shootout? I can't find it right now (tired as expletive).

oh and to the other guy:

Notice how Randy mentioned that the SMSP header also beat the Hytech in that test? I don't think anyone involved in that test sells SMSP products - doesn't that kinda shoot down the 'biased testing' theory? lol

 

cant wait to order my header from Randy.

 

And that one time at band camp "oh snap hytech lost one header test" I'll ignore the other kabillion of them

And this part should interest people - on an "untuned motor with no exhaust" - because I drive around like that alllll the time

yes a header made in the USA simply must be made than one in China, it must it must it must.

AYFOOYM seriously you must think that places that get these kinds of contracts are some little tiny place in the middle of a rice patty. Places that do contract work are on a scale that puts even DC massive facility to shame. These are the kinds of places that invested in million dollar mandrel benders long before anyone cared.

Of course I'm going to put the header I bought before other ones. It wasn't a matter of money or limited selection but the benefit of being able to talk to and see these headers being used.

The fact you turn a nose up at not being waited on by Hy-tech shows how imature you are. That's business, when you pay his bills instead of the formula atlantic guys he can spend more time with you, it's not a matter of respect or anything else just priorities. Next you'll yell at the bank teller for the business line or the VIPs at the club.


and this test lol

https://honda-tech.com/zero...ge=18

"Hytech 4-2-1 Stainless Steel -$799 comes with donut gasket and flange
One of the most beautifull headers i have ever seen, flawless welds, great craftmanship. Good price for a Stainless header , especially from someone of Mr. Grudynski's caliber. This is Hytechs first Production header. Hytech has been known for his much more priced custom headers and he is famous for his higher end headers that use his reversion chambers. This is a mass produced header that he is now offering to the market. Made the most Midrange power of all the headers we tested"

the header above proves my point - a one off custom non finished race only piece and a without being able to use a full length radiator to battle a production piece and produces mystery dyno figures with no exhaust attached.

It's interesting that you say "all" headers have the bracket when none of the ones on the site not those I've seen nor almost all the pictures have them

Even beyond the numbers the "quality" was more important. I like to do things once. But then again I never bought skunk2 cams so what do I know about "good" parts

ahahahahahahahahaahahahahahahahahahahahahahahahaha hahahahaha

I really didn't mean to pick on one company - they make a decent though IMO not comparable product - I mean if were gonna argue something meanial lets talk nos it's wayyy more cost effective per hp but then not applicable either. RMF stainless headers are "NOT" under 800 bux which is my original point of comparision not that anyone reads this stuff before responding

 

Suavacito:

Have you never been in the all motor forum before. This has been discussed a MILLION TIMES.

You are going to get schooled, brother.

Randy(RMF), Dave(smp), DTR, all make way better headers then the one you posted up. Do a search before you make yourself look like an idiot.

And Hey, if your all for the bling welds and the shiny SS then thats you. Yes SS will last longer of course. I want the header thats going to make the most of what its built to do, make power . You can bling away if you want, its cool.

 

wow search never thought of that. Never thought of spending 3 weeks doing that or the 25+ phone calls or hundreds of miles I've driven between shops and friends and meets. It's all about internet chit chat.

when your sick of "dicussion" post some proof.

And for a moment consider that if peoples sole decision for buying parts was a few hp, turbo converts would own this forum.

And with your line of thinking I better not find one OEM replacment part on your car because damn if those fake altezza lights do the same thing for less who cares if they fog up right.
