I got my DC Sports Race Header yesterday at my office around noon. Got home around 7p.m. and went to work. Jacked up the car and left it on the jackstands. Taking off the stock header, downpipe, and Catalytic Converter was fairly simple. No major problems there. Removed the sway bar and then I was ready to slide the RH header in. First I attached all the sensors including Caspers 02 sim. Slid the header underneath and it went in easy. Bolted the header up,(as well as the sway bar) secured all the 02 wires with the provided tie wraps and I was good to go. Took the car out for a spin and was very impressed. I could feel alot more power through the midrange. I also felt the car was more responsive. Aside from this the only problem was that the header is touching the sway bar. It would rattle on and off and hit at certain points. I have the ESMM's at home and I am going to install them as soon as I get off of work today. Hopefully this will take care of the problem. I'll keep ya posted.

**Edit: Ran it a few times hard and drove this morning and No Cel! :driving:

does anyone have any dynos yet? I need to compare my jackson race header, because now im not convinced that its making as much power as other headers...and WTF is up with dc sports adversting 44 whp gain...bs or what? :dontknow:

Well I plan on getting a dyno either this week or next hopefully. Sadly I never got a baseline dyno so I really won't be able to show the exact gain.

how is the sound while normal cruising and do you have aftermarket exhaust system and sway bar or are those two things still stock on your car. Please keep us updated because i have my dc header on order also but i heard it is not released till end of May since it is the ss one.

Well, you know the rule...2/3's of what the manufacturer says. But, yes, by everything that's being posted around here, the JR does seem to be falling behind.I haven't seen any dynos as impressive as the Toda header yet, there have been dynos of all 4 in here somewhere. Toda, comptech, and DC all have similar topend gains, but Toda has that big midrange torque. Big torque gains right where I spend most of my driving at. It's just getting too loud to run around at 7 grand anymore, and I spend most of time in the 4-6k range, which is where the Toda shines.

But then there's the fact that I can get the DC header, ITR mani, K-pro, and have it tuned for the same amount of money as the Toda header alone. It's temping. But so far I've got it in my head to wait for the Toda.

I still have the stock sway and stock exhaust system. I believe it's just a lil deeper but not by much from what I notice. I still hear the intake over it easy! You gotta remember that the car always sounds different when your driving it compared to when someone else drives your car and your outside listening to it.

Hey chuck whats up with that dyno man? U should have at least broken 180...huh weird. For some reason maybe all that spark plug stuff is skrewin sumthin everything up...who knows..Anyways should people expect like a 25-30 whp gain out of the dc race header?

The 44WHP number was with the header, intake and exahust I believe. The DC vs Comptech dyno showed DC with more low and high with comptech havng more mid. The car that they were tested on was tuned for the Comptech header. I hear that a differnt Vtec point will yield more power in the mid range with the DC. Seems to me K-pro and the DC header were meant for each other.

Well we pretty much almost have the same gains and my uncorrected was 202 whp and 146 wtq. The 44 whp was with intake, header and catback and it probably wasnt peak power...prolly some where in the midrange :dontknow: . With companies nowadays, you never know what they advertising.

true dat.

but isn't the dyno of comptech vs dc... the dc falls short at a miniscule 5500-6000 rpms which sorta has a vtec dip once again.

and the whole "midrange is the best" thing just depends on people's situation. personally i want more power from 6000-8600rpms, cause when im on the track... (and no not the stupid drag strip, im talkin laguna seca, thunderhill, streets of willows, buttonwillow etc.) my rpms reach no lower than 5000.

so the dc sports header seems to be doing pretty good in that. and based off that dyno, theres a LOT more low end which is what i drive at. i shift at 3,000 rpms for daily.

and for anybody else concerned about gains, we're talking about a $280 header. the dollar/horsepower ratio is unbeatable for race headers.

What people need to understand is that it is TUNING that is setting these headers apart from each other. That VTEC dip can be taken care off w/ a little tuning which the CRH had.

DragonRSXS, what is your suspension setup? Is it the Eibach's and that's it? or do you have struts, camber kit etc? The guy from DC sports wants to know. They are trying to figure out all possible causes for the header contacting the sway bar.

Thanks.

Do a search, a guy tested the comptech with the DC back to back on the same dyno....I forget his name. Schuessler or something.

It gave more than the comptech, and I'm pretty sure the comptech will put the JR in the dirt.

yeah, and he was tuned for the comptech and not the DC, DC still did a little better. a few spots it was below the comptech, but i think tuning would fix that

Henry- I posted in the TeamDC5 chat thread about that.

And yes, I think a real world 25 HP gain is prolly not going to happen. You will prolly, however, see a good gain in certain places. I look at that dyno between the comptech and the DC and I see a peak gain that is very similar, even to the point that what temp the motor was for each run could have switched the peak gains if the temps were also switched. In other words, dynoing the in reverse order that they did the dynos. We all should know that temperature can change a dyno by a few HP. but then look at the different gains at different points in the graph. THAT'S what it's all about, and that's also why I'm still attached to the Toda header, even given the MUCH higher price. Not that it has much of a higher peak, but it has LOTS of more usable torque in the midrange, which is where most ppl do most of their driving.

A header strictly for dragracing on a budget? DC has that obviously covered. But the fact that I'm more about what the car is going to do in day-to-day driving, the Toda has much more USABLE power. As far as the comptech goes, I certainly wouldn't kick it out of bed, as they say, but for the price, I'd definately go to the Toda. If the comptech was more competively priced, like in the JR range, it would be more of a contender.

Correct me if I am wrong, but from what I recollect the Toda got that impressive midrange due to a lower VTEC engagement point...close to what Toda TUNED it for. The ecu might not have been tuned to accomodate the Toda header, but it just so happened that the base vtec engagement point of the k-pro when the Toda was installed was close to what the Toda flash engages at. Something to keep in mind before assuming Toda has great midrange.

i would agree at this point that the toda header offers the very excellent midrange gains. but mmmotor is right, they have a reflashed ecu that was specifically tuned for best results on the toda. and personally even if the dc header doesn't get anywhere as good as overall gains, it's still 1/5th the price.

with the dc sports header available. it's just making the rsx n/a legacy even more easier to achieve. with all the new rsx guys coming along, all they would truely need to reach mid to low 14s even with the most average driving skill is less than $1200. i would say that's an amazing $/hp ratio.

cold air intake - $250
hondata ecu - $600
dcrh ceramic - $290

and i bet even with shitty michelins a minimal time of 14.6 can be achieved with the average driver. had it been if everyone was willing to remove their catalytic with only the comptech and toda header was available (which was the case) then it'd be in the less than $2,000 range which is not as magnificent.

so yeah if people really could afford the extra midrange on the toda for $1200 w/ swaybar. then it's safe to say they can do what they want, for whatever goals they want to achieve for whatever situation.

but i bet my shiniest penny (yes penny not a quarter cause im cheap) that the dc header should be backordered soon enough by the insanely low price for something that should have been this price to begin with. :tonguegri
