DC Race Headers

[topendspeed]

Ight i'm looking into getting dc race headers for my civic si sedan, the problem is i don't want that engine check light to always be on. Is there any way around that anyone?
I appreciated

there's only 1 header man and there's also tons of info about this already. that's what the search function is for.

You could buy the scangauge II to fix that problem..its only $160 and it has a lot of great features.

And you should get outa the habit of calling them DC headers,..... More like Pilot Auto race headers!

Or just buy a de-fouler, cheap, and does the trick. I've mad my header on for close to 5-6 months now. No CEL>

You should get the Vibrant rh w/hfc. MUCH better craftsmanship, will most likely last a lot longer, and you might not need a defouler with it. Most people with this header are not throwing Cel's. I am, but that's another story.

bleh forget the vibrant with hfc.. who needs a cat anyway.. the dcrh is half the price and provides better gains.. by the time the header goes bad if it ever does he will either have another car or will have something more serious that requires a larger diameter header anyway..
the dcrh has been proven to be the optimal size for our cars without FI.. as soon as u go SC or rediculous setup with cams ur gonna want the vibrant or buddy club header because of the thicker diameter.

^^what are you talking about...its identical gains...besides dc is 2.25 vibrant is 2.5 meaning that it has more aftermarket compatibility with skunk 2 and greddy etc. etc.

you are incorrect sir.. they are not identical gains.. and even if they were the dcrh is the better buy. the only time the vibrant and buddy club headers are useful is when you have a supercharger or a rediculous cam setup which isnt possible rite now anyway.. as it stands right now on a I/H/E setup if you dyno the dcrh vs the vibrant you will lose power since the vibrant is too thick for that kind of setup you lose exhaust velocity..

Even X experienced this when he switched from the dcrh to the bcrh.. do some research before you start giving people false information.

^^yo dude did you not read the current threads? x admitted the mistake was that his intake was tuned to only slight mods..the reason why it didnt work with bc headers was because he tuned his intake and used a stock exhaust, when he replaced it with bc headers he got another exhaust thus releasing more flow, which is why people are mad that his intake only allows for great gains with slight modification, making him release a version 2 for more modded cars..YOU do research

edit:sorry for that..its just that i just did 2 days straight of research just to get the right header..and i'm sorry i blasted on this topic...

[Daishi]

his car has cams smart one... which is also why he had a v2 for cars with cams.

[solidust]

look dude i said sorry ok..i could argue about this all day but just read the threads

edit:heres one X-Intake Dyno results.........

but I am in the process of prototyping the V101 for X, the V1 didnt make "expected" gains on a more modified car, like mine, (no cams though)... so he has tuned out another maf dubbing it possibly the v101 to see what it turns out like... anyways i opted the dcrh because of the price vs. gains but if and when i boost ill definately change it out for the BCRH

ditto.. i plan on doing the same thing. what does x plan on doing for people who already have the v1? when this v101 comes out if it proves to give gains.

this is just speculation I dont even know if it will provide gains, i dont think he will be marketing the v101 either (to my knowledge) he just ever so slightly altered the v1 to my setup to see if it provides any gains...

i see... im still on the fence on whether i wanna try for the comptech supercharger or go all motor.. get some cams and the v2 intake and see what happens.. then eventualy kpro if that ever comes out.

im looking at the skunk2 cams and for stage 1 it says that the upgrated retainers and such are not required but recommended.. ok that makes no sense either its required or not required lol.. because if there is a chance of something breaking then yea its required lol. what could happen if i dont get them...

Get the dcrh.

Then, go to autozone, get the HELP brand sparkplug defoulers p/n 42009, put one of the defoulers that comes in the pack (there are two of them) in a vise (not too tight or it will bend) and move up size by size with drillbits till you drill out the little hole in the end to a 1/2" hole. That is the defouler that gets the o2 sensor screwed into it and then screw that defouler into the untouched defouler and then plug that into the header bung. Any questions, pm me.

[strutking]

we have defoulers available
