the best headers??

the best headers??
It seems like the price of headers range from 300s to 1200. Are the comptech ones the that much better then the cheaper brands? They all are made out of the same material and all claim the same HP????? I just bought a 03 S-type and I am looking to start to slighty modify, exhaust, air intake, chip, what you tell me??

Comptech is the best for fitment reasons and quality control. Very few if any have complained about their Comptech headers not fitting right or having resonance issues.
Comptech is the only known header to work in the '03 CL-S 6speed too.
If you go with the cheaper brands there is a possibility of it not fitting and then you need to modify the headers to get them to fit. Couple of different common issues is the downpipes not lining up with the A-pipe, the O2 bung not being in the right spot so it hits the oil pan, and resonance (think of the noise you hear when blowing over top of a pipe or like a glass) from like 2500-3000 rpms.
You don't really have to worry about that with Comptech headers. With other brands, its a crap shoot ... you may have no problems but you might. I have no personal experience with any headers other than Comptech and Stone Racing. Stone didn't fit for me, two different tries (from the 1st and 2nd batch), Comptech fit, no problems no resonance, no issues.

I didn't really feel any difference immediately but after a day or so of driving it...WHOA! It REALLY pulls hard to redline...before, the car would seem to flatten out at around 6500-7000 RPM and now I find myself bouncing off the rev limiter.
I know it's not a name brand and it wasn't expensive, but I am really happy with the purchase...and I wouldn't hesitate to do it again.
That and the CAI are the only engine mods so far.
Good luck!

The fit-and-finish was very good--though the match porting inside the runners wasn't quite as good as the Comptech header. It came with all the gaskets and bolts and I have no issues with it at all.

And reliability? It's a header. It's stainless steel. It won't rust. It fits perfectly. The 02 sensor bung was in the correct place. It came with all the right gaskets and bolts. What else do you want? A stupid Comptech stamp? Take it down to a local engraver and have it engraved then.

I've got a set of AlphaWerks headers.
I love them. I had them since August of 04.
No problems yet.

Don't get me wrong, If I found a set of CT headers used for a good deal, I'd jump on them...a good deal being around $400 MAYBE $500. Any more than that..no way...i'll just keep my "crap" stainless header or just stay stock. $1,000 bucks buys a lot of things.

If you are happy with the ones you have and don't mind swapping them if the welds don't hold, no worries. If the HP gains are the same, and they more than likely will be since they all copied CT's design, then good luck with them.

The Final Answer!
Alright, emailed both Comptech and Nexus Industry (alphawerks) and have found the final answer to our question about which is better power wise. Nexus Industries claims that their headers only produce 13HP more than stock. Their dynos indicate 29 or 30 at the wheel but only achieves this amount b/c of their intake addition when doing the dyno. Comptech on the other hand claims that their headers produce 25-30 alone, w/o intake or any other mods at the time of their dynos.
Hope this answers your questions. Now is the gains worth the extra $700 you have to cough up? It's up to you!

So when using Alphawerks Air intake along with their headers created 29 to 30 WHP or at the crank?.. That's 16 to 17 ponies with a air intake added.

those numbers dont mean shit because they make the environments perfectly ideal to extract the most ideal numbers .. and they dyno the hell out of the cars until they achieve the numbers they want ..... so they really arent that credible.
Anyways
THEDREAM I BOUGHT THESE HEADERS TOO ... THEY ARE ARE ARE ARE INFACT MEGAN RACING HEADERS
first look i took at the three to one part of the header is stamped with megan, but looks like it was buffed out.

Note: If you plan on installing them yourself, its a PITA!!! Make sure you have jackstands and good tools...and I REALLY recommend having airtools. You have to remove the strut bar and such to reach the rear manifold bolts. The worst bolts are going to be the catalytic converter bolts...they were really rusted on my car- I had to cut them off. The header comes with new bolts so It doesn't matter!
Good luck to you!
P.S. I'm taking my car to the track this weekend- it's only an 1/8th mile but it will give me a good idea of my gains. My best ET before with only a cold-air intake was 9.33@78ish (give or take a couple mph), with an average of 9.5-9.6.

Here's my angle: No one, not even CT claims a performance improvement under 4000 rpm. I don't race my car. It's my daily transportation. Sure, I'll have fun every once in a while and stand on it, but I can count on two hands the number of times I break 4K on a daily basis.
Our cars are plenty fast, and if you're regularly winding it up past 4000, you are in ticketland unless you drive around all day in first and second gear. I have never used a cruise control more in my life, just because she'll crack 100mph without breaking a sweat, which usually makes me break into a sweat! Every time I see a Crown Victoria I have to glance at the speedo and hope the mphs weren't in triple digits
I'd love to put headers on my car, and I think I'm as exasperated as the rest of us with the "which brand is the best" debate--wanting to get CT, but can't even justify the cost of the Alphawerks--but I just don't know if it's all worth it for at most a 12% horsepower increase at an rpm range I rarely go into.

For those of us that do have the itch... 30whp is a huge gain for a bolt-on mod. With many NA cars, you can't expect anywhere close to those kinds of gains from just a set of headers.

I had some of the same thoughts before I bought mine, but I’m glad I finally did.
I don’t rev the engine to 7,000RPM on every shift, but the power is there if/when I feel the need for it.

I just went back and now if you add them to the cart it shows 550.00...so I called and they said that is the price $550.00.......
Sorry, looks like I'll be going to CCC to look at some Comptech's

I emailed the guys at Nexus Industries and they claim there's no way the CT headers are putting out 25-30WHP. They said that was false and the headers are putting out the same WHP as eachother.

Yes there are hard dyno numbers out there, but all are from CompTech who of course have the ability to post biased numbers (so Nexus Industry claims). I have NOT been able to find posts from other people with their own dyno results with ONLY CT headers installed and NOTHING else. Post a link to one if you know of it. Please please prove Nexus wrong b/c I for sure do not want to spend $1100 for a product which Nexus claims is the same as their $400 ones.

The gains on the headers are all the same.
The confusion is the 32whp gain on the Comptech dyno. The 32whp gain is the MAX gain. Its not the peak gain which is what a lot of people will look at on a dyno.
The 32whp gain is somewhere around like 5500-6000 rpms if memory serves. Its simply that when they dynoed stock, the car got like lets say 155whp @ 5500rpms, and then with the headers the car put down 187whp @ 5500rpms .. A gain of 32whp. Does that make sense?
Peak gains for headers is like 15-20whp I think. So if your dyno shows you putting down 195whp peak with no headers, you'd be putting down 210-215whp peak with headers.
Its all about how you interpret the gains. Comptech has been marketing a 32whp gain, but the gain doesn't occur at peak, so you don't see those numbers when people dyno their cars. Most people with the standard I/H/E will dyno around 215-220whp, working their way closer to 230whp as you add on additional items like the pulleys, Unichip, maybe Thermoblok spacers?
Hope this makes sense.

Good post LiQiCE.
Here's some more details from Comptech
http://www.comptechusa.com/store/cldyno.html
Notice that the gains are 6HP or less all the way up to 5800rpm.
That's why myself and others will say the Icebox is the better bang for the buck.
Look at the Icebox dynos and you'll see that 6HP increase comes in at 2800RPM.
Also, I'm willing to bet that the headers will give better usable HP sooner with an Icebox.

That's why myself and others will say the Icebox is the better bang for the buck.
Look at the Icebox dynos and you'll see that 6HP increase comes in at 2800RPM.
Also, I'm willing to bet that the headers will give better usable HP sooner with an Icebox.

I had a TL-S w/ all the comptech goodies, including their headers (which I bought used for $600.00, and then sold for $550.00 to a member on this board -- who still loves them! that's how reliable they are... they've been on three different cars... an Accord, my TL, and this guy's CL).
The advantage of the headers, one that no one has mentioned yet .. is that when you are at WOT from a roll, and say you're at the track... since all your upshifts drop you near or very close to VTEC territory ... and since this is where the headers add their power .. the headers REALLY shine in terms of your ET and trap speed. Just b/c they don't work under 4000rpms is not that important at the track. That's what superchargers are for .. low end torque.
