Re: (bakerboy0642)
hey baker. You can pick up a decent set of headers on ebay for about 60-70 bucks shipped. Just search for any DC style 4-1 headers. They might not get you the usual 10-12 hp increase but they will definitely help. Hope this helps bud.

exactly. ebay foglights are legit. also, cheap headers crack, don't line up properly, and often have poor welds that restrict flow

lol....the usual 10-12 hp increase lol. ebay headers are whatever. just stick with oem, the topend u gain from a header on our motor isnt worth the bottom end u lose IMO. so yea.. grounding kits are ok as long as there not liek one of those 8 ground spider kits. thats just retarted. u really do need to search. thats why its bolded in red..

It's not random how the brand affects hp/tq at all. Header design is a very serious business, and while essentially they are a bunch of tubing, the reason you are paying big money for the brand name ones, and $80 for an ebay one is the R&D involved in building a header.
There are many things to consider, such as runner length and shape, collection methods, and sizes which include actual tubing size and any types of flaring of the tubes.
Companies invest lots of money in designing a header that will produce maximum power gains over the whole powerband, low end, top end etc. For example, if you were to make a 90 degree bend straight off of the block, straight down to a collector, you would see a different gain or loss than a 70 degree angle with a curve in the pipe to the collector. Big companies test many designs on the dyno to determine which one is the best overall. This is what you're paying for in a big name header. Not to mention, the quality of materials will be much better in a brand name, as well as the workmanship. Welds on a cheap header can be rough on the inside of the pipe, which can disrupt exhaust flow ever so slightly, so that there will be a noticeable power loss vs. the design they copied. Also they can be welded quicker, with cheaper wire or less heat, causing them to crack prematurely.
Stay away from ebay headers.

Hey Awang...i dont know where you get your information from but whatever. Have you ever bought headers off ebay?
I bought mine off there, DC-S headers 4-1 about a year ago. Never had a single problem with them. Install was quick and painless. Took it to get it tuned and dyno tested and the headers alone boosted the hp by 10. Silver, yeah you are right the high end you gain isnt really worth the low end you lose unless you are planning on getting it performance tuned so that you have power all through the powerband.
Either way dont knock Ebay they got some good stuff. They just get a bad rap. Why pay more for a company logo like DC? Like you are gonna have your headers out for everyone to see anyways.

on a NA civic? BULLSHIT! also, i haven't bought a header off of ebay because i'm smart enough not to. they're cheap for a reason you know...
also, why the hell would you dyno your car after just adding a header? where's the intelligence in that?

Re: (awang)
Hes most lickly lying.... i have never even heard of a civic geting 10 horse power from a single bolt on... Also there are other brands besides DC. Recently i have been hearing bad things about DC's headers. Cracking after a month or so. The ceramic coating burning off..... so i called up megan racing a got a header from them since i allready had the midpipe they make.
Point is dont ever go for exausts, turbos, wheels, and any other "performance part" off ebay. I wont even buy fog lights of there after a buddy of mine bought a "carbonfiber" hood. turns out it was just a oem hood with a carbon sticker on it....
Whats a grounding kit suposed to do anyways besdie add more wires to get caught up in ****?

Re: (bakerboy0642)
it's your money. in MY opinion, it's not worth it. if you do get it, yes, you can install it yourself. in fact, i advise you to do it yourself, as opposed to taking it to a shop. NO- you do NOT need to re-tune your car.
LET ME SAY THIS OUT LOUD AND CLEAR: NOBODY NEEDS TO RE-TUNE THEIR CAR UNLESS THEY HAVE DONE A SIGNIFICANT AMOUNT OF MODIFICATIONS.
No you do not need to get a after market exhaust system at the same time. You won't lose low end unless you increase the exhaust piping diameter by a lot.

things are never as good as they look on paper...not even close in this case. you'll be lucky to get 2. you'll get more like 1ish at high RPMS

not rev higher, the power curve is shifted later in the engine's usable rev range.
really the d17 isn't a good engine for bolt on power. best thing without spending a lot is n2o, with an intake and exhaust, the header might even help here, and a fuel controller to balance out the air/fuel with the n2o. otherwise a good turbo set up like dezod's kit which runs atleast $4k, usually $5k+, to get everything and get the engine running smoothly.

You may have done for other cars, but not ours mate. They are worth it on many engines but not the d17.

theres nothing wrong with buying things OFF of ebay...just be careful what u buy OFF of ebay. theres generic brands and legit brands both on ebay. you can get megan headers on ebay for a good price and those are not generic. today i put back on my oem header that i painted a ceramic black..i got my low end back in..and didnt care about the 2 hp i lost up top...again. get a nice intake, a nice catback...maybe a high flow cat or test pipe if u want to go that far. get a grounding kit to keep ur car feeling ok.. u know? Gearbox has gotten a hyper grounidng system gt or some crap like that and he says his acceleration is alot more smoother and doesnt sound liek the motor is about to die. get those little things and u should be ok. work on ur transmission bro. clutch and flywheel and short shifter and all that crap makes the power go to the wheels alot better and ull feel a big improvement. work on ur suspension. dont invest too much into our engines if ur not turboing or swapping out k? headers are usually good for other cars. u can put headers on a wrx and gain a good 10-12 hp to the wheels...even on the b series motors ud gain a good 6-10 hp...not on ours...whole different motor honda decided to make..and it sucks...its ok tho...suspension.tranny.basic bolt ons...ur good

personally ebay is a hit and miss and if ebay works for some power to them some parts have worked for me and never had a problem brand names are no biggy thats why people do custom work and build custom cars not everything has to be branded to be good and heck even if a ebay header makes you gain 5 hp be happy thats 5 you didnt have and money you saved we drive hondas not formula 1 cars

Re: grounding kit/headers, are they worth it? (crazybluecivic)
this thread makes me laugh
1. never get anything off ebay for your car (think of it this way, you've got three choices, however, you can only pick two 1. fast 2. reliable 3. cheap)
2. don't waste your money on a grounding kit
3. headers would be good on a corvette or something like that, don't worry about putting a header on your little 4 cylinder 1.7 liter POS economy motor. If you had a K, then you might notice some gain from a GOOD QUALITY header.
4. DC sports is a shitty brand of header
5. to be honest, the only way you are going to get good, reliable power out of your D17 is to boost it, sorry, that just the way it is.

if i remember correctly, WRX's are factory turboed. If you have a turbo, doesn't that eliminate the header in place of an exhaust manifold in which is connected to the turbo itself. LOL. Now, just to be fair, you can still have a header(s) on a supercharged application.
