Ok guys/gals,

Unless I've missed it, I don't think anyone has purchased the cermaic HP Header....the shorty version.....so I gave it a try. My thoughts and approach is this:

1. HP doesn't have the carb exempt crap that DC markets on there products.....so that was my first reason..maybe a better performing product has they claim!!!

2. They only offered the Header w/ high flow CAT....in Chrome..which I will not purchase a chromed product of any kind..especially headers!....so I went with the top section only

3. Now DC sports stated that the downpipe wasn't of significant length to constitiute developing an addtional two piece header....so I thought I would give the factory dual walled downpipe a shot.

4. BTW...I'm getting to the results......hang in there[IMG]i/expressions/face-icon-small-wink.gif[/IMG]...if I didn't like the downpipe I would possibly buy the stainless steel version once the O2 sensors where corrected.

5. If that didn't get corrected I would have a custom downpipe made...(got conections)

6. So with all of these options...i bought the Header from NOPI...$222 (I think)

7. Product was of "Great" quality and fabrication.

8. Fit perfectly without buying new gaskets and dounut sealer with 23,000 miles on my car. Installed in about 45 minutes without lifting the car. Reinstalled using all stainless steel nuts, washers and bolts for added protection and apperance.

9. Test drove.......now with all you guys bitching about not a real impressive gain from DC's shorty header I was a bit sceptical about my investment...but as it turned out I was "VERY" pleased with the results...I would be interested to compare the two products. If you look at our factory header once removed you can see the various design improvements with the HP design. So if indeed the downpipe helps as well...then just another mod waiting to happen.

10. Gains where seemingly increased at 3000 and above evenly, with a very noticable difference at VTEC wild lobe engagement.

11. Anyway I hope this helps people as I've debated for a year now on this investment mod...the looks and performance is of very good quality.

12. Rating so far......7-10...Peace guys/gals

does it make it louder, like a deeper tone from your exhaust or engine in any way??
always wondered that...and i also wanted to get the hp header...but hi flow....when they correct the O2 sensor that is

 
Rep Power: 0

No difference in sound...my car is plenty loud already..so if there is a difference, I couldn't tell..LOL!. The O2 sensor situation I'm refering to is the stainless steel downpipe only version, being sold on ebay for $150. The HP full 4-1 header doesn't have that problem that I'm aware of?

Carb exempt crap? Anyway, I'm not in that disappointed group. I have the DC Sports stainless header and I am extremely pleased with the end results. Combined with the CAI & exhaust the gain is excellent. I'm very pleased with both the quality of the product and the performance.

Cool Allman, when I got my DC header, I wasn't expecting much, and thats exactly what I got. Downpips is still my bottleneck. Sure do look nice under the hood though.

Did you happen to measure the diameter of the pipes before installing? I've noticed with the DC, it's about 1mm larger in diameter than stock for each of the small pipes, and the bends are a bit straighter. Also, the little square divider in the collector of the stock header is gone.

I got a DC ceramic, which I paid about $230 shipped. I was thinking about a HP ceramic and other generic brands, but I stuck with DC just because they are repetable and got that CARB crab which all Californians need. So I guess I paid merely $10 more for all that, which is worth it.

Wait.. so did you change the downpipe or did you just install the short HP Ceramic header? Meaning, just the bolt on w/o modification. thanks

Sounds like a good deal on the hp header. I am sure produces better results than dc's does. Thanks for the review ALLMAN. I think I am going to wait for the corrected 4-1 header w/high-flow cat. Hopefully, it will be out shortly.

I am pretty sure I saw the ceramic header w/high-flow cat on some website.

Mbow - Why would the HP shorty header produce better results than the one by DC Sports? What are you basing that on?

hey guys i have the HP chrome 4-1 headers with high flow cat system. all i can say is holy $h!t. if u can get that system go for it. and i will tell u this i race my friend that has a 4dr ex 5-speed with aem cai, dc shortys, and a muffler. and he use to beat me everytime i have a ex auto. but i bought my injen cai, my hp header and cat system and got a custom 2.5 cat back witha skunk2 muffler and i can tell u this that it will beat him now.

First ,

1. I'm not degrading DC Sports in anyway on their product line...they made great products......but let me speak from much experience in working with various materials, designs and manufacturers, ...just because they are reputable does NOT mean they've developed the best peforming product!!!!!!.....hence the comenent "GENERIC"..."BUT" what I am stating is that HP markets their products from a carb exempt standpoint....so obviously not a California application....which I do not live in.........so my overall point is this, I gave it a try....liked it....and recommend it!!!!...............also any company that offers a warranty on a product is always a big plus.....I can't recall DC offering one?????....can someone clarify???....I wouldn't see why they wouldn't.....but as a rule of thumb...do stay away from manufacturers that don't.

2. No, I have not replaced or altered my downpipe as of yet......this was simply options I'm planning.

3. I checked, and called HP concerning a ceramic Full Header..and as off my call...none were being made......BTW, I wouldn't always trust websites....I've found many many errors with the header application. Some call Chrome...Stainless Steel...BIG DIFFERENCE!!......some call 4-2-1...some call 4-1......some say too piece some say one piece...some don't say the shorty version...etc......so, so far the most confusing product I've came across yet.....with the descriptions being misleading.

Peace![IMG]i/expressions/face-icon-small-wink.gif[/IMG]

I would automatically assume the HP shorty header would perform better than the DC one simply because they do not have to pass CARB requirements. Getting CARB certification usually chokes out some performance.

 
Rep Power: 0

That still doesn't offer any evidence whatsoever that the HP shorty is a better peforming product than the DC Sports. I'm not trying to start an argument here or say one is better than the other, but if you're going to make statements like that, lets back up them up with some facts.

By the way, DC Sports most definitely offers a warranty on their headers.

Thanks SQCivic,


I figured they did offer a Warranty...just never came across one in my reading of the Header Specs....Peace .....and hopefully someone will dyno!![IMG]i/expressions/face-icon-small-wink.gif[/IMG]

Hey i was just wondering if you had to make any mods to your motor mounts or anything! b/c i've read in an earlier post that someone had to remove motor mounts and it didn't bolt right on like it was supposed to. thats mainly why i did not get it b/c didn't want to make any additional mods just to get this hp header!!!!!
thanks

Speed Racer32,

Just speaking from experience, and not that it is representative of everyone..."BUT"...chrome headers are not as corrosive resistant as ceramic nor as good of an insulator..and many I've had has rusted before the life of my ownership was up..so just by price comparison alone you can see the difference in protection with

a. Chrome.....then
b. Cermaic...then
c. Stainless Steel...but

Stainless will also rust...just much more corrosive resistant than most carbon metals as well as probably outlast the ownership of your car(average).... I don't like the blue color that stainless turns under heat influence nor the price tag associated...but cermaic, well kinda the best of both worlds....if coated well, then will last many years and fight corrosion well, maintain its apperance well...and cost about $100 dollars less than Stainless(Average)..so that's my opinion.

GreenVenom,

The HP header I got was the "Shorty Version"..meaning the top section only for the EX....which I don't know if it will work on an LX..as I've never looked..but my wife has a 2002 LX sedan so I'll check her car for you (1028Civic).,...anyway greenvenom.....it is not a full 4-1 header has the Chrome Version w/ high flow cat...Search "HP Headers" for plenty of info for that version that had the problems thus far...Peace..BTW..I'll have pics up soon!![IMG]i/expressions/face-icon-small-smile.gif[/IMG]

sorry I'm a little confused.. I was also looking at the hp shortie... my question is in the long run over time... can both the short an the long be jus as benefitial once you add onto the short?

SQCivic, I'm not making any claims, nor am I the one who originally made the claim. All I'm doing is trying to offer you one answer to your question. Perhaps the flow of exhaust to the cat has to be slower in order for the cat to work at it's max, to gain CARB exemption. I don't know, I don't care, take it with a pound of salt.

I base my opinion on the fact that dc's i/e/h combo only made 5hp. Import tuner shows an intake alone making 4hp. That discredits dc's products as far as performance hands down, no angle to argue from. Dc only offers a shorty header and not in the 4-1 configuration when it is a known fact that these engines peak in hp at high rpms which a 4-1 header facilitates. Plus, the hp header combo comes with the high-flow cat and it goes w/o saying that it will also increase performance. Lastly, while it's no secret members have had problems with the hp header, they usually report a noticeable difference in performance according to their a$$ test. I can't really recall anyone saying they noticed a performance increase with the dc header.

Yea, dc's products look very nice and are of the utmost quality and appearance. However, I don't show my engine bay off and never pop the hood for any reason than to wash the engine. Plus, if I am going to buy a part that is supposed to increase performance, that is what I want, not a show piece.

Anyhow, yea your are right, no direct comparison of the 2 products. I am making assumptions and have no problem admitting to that. However, dc's combo making 5hp is all I need to know.

Dave - No problem man, just looking for concrete evidence that one is better than the other, that's all.

Mbow - The DC header is a 4-1.

When I purchased my Header from NOPI, they didn't have a picture available to view...they've just uploaded that since my purchase....which is an incorrect image....it is just the upper section ONLY for $222..and not the lower downpipe...probably just a generic image as most website do...Peace!

Hmmm.....haven't looked for the dc header to purchase or anything but seems like I always read that it is a 4-2-1 design. If this isn't the case, please excuse my ignorance on that point.

Yes DC is a 4-1...again just another example of misleading product info......I can't for the life of me understand why they can not get this product discription correct........UUUUUUUUUGGGGGGGGGGG!

Actually, I'm starting to become skeptical of the 5 hp gain claim by DC after installing the I/H/E combo. According to import tuner, they got about 4.2 horses after installing the TCS on a 2001 civic ex, plus another 1.8 with the Hayame intake for a total of 6 hp. Unless the DC header will give you -1 horse, the number is probably not very accurate, even if you take into account for standard deviations of the dyno.
