hey guys i've been looking into it alot for the past week i really want to put headers on my civic but i've been hearing all different stories. Basically i need some people to tell me, they put them on and everything worked fine. lol

-The engine light didn't come on
-Both O2 sensor are able to be put back in
-No difference in gas mileage

Also can headers be bolted on to original exhaust system? I know its best to do a full system and in time i would like to but for now i have limited money. I have researched this topic and didn't find as much info as i would have liked.

You might notice a change in MPG, but only like 1 to 3 mpgs, nothing crazy like 10mpg less. Yes, when I did it, everything worked fine wihtout problems.

Personally, I would not invest money into a header for this car. Not if you're keeping the motor stock, anyway. Especially if you are bolting it up to the stock exhaust system. If anything, you should get a cat-back system (or even axle-back) before getting a header. If you rework your head, sure...but if you just want something that 'looks cool' when you pop your hood, forget about it. You will not see any substantial performance gains at all. Not only that, but you will create a chain reaction of issues you will have to deal with.

Chain reaction of issues to deal with? Not really... what do you have in mind?

Yeah I bought a JVT racing header that bolted right up to the stock down pipe and they have worked fine. Nothing noticable in hp but it worked great. (None of this matters anyway, cause im gonna BOOST MY BITCH!)...soon anyway.

lets say you got long tube would you be able to get rid of ur downpipe and go straight to the stock catback

From what I hear the downpipe is double insulated, so if you can get a header that goes all the way back to the cat like the dc 4-1 then yeah you should and could get rid of it!

Great to see the same old questions are being asked...

Headers on the d17 are pointless....

Honeslty so is boost on it. Ive had both, save your money buy nitrious(ive had that too) for some quick races. Boost is expensive and hard to tune on the d17 when its done right

Throw on a Catback exhaust get some sound and be happy

Ajhdragon, When You Ran The Bottle, How Big Of A Shot Did U Use, And How Long Did Ur Engine Last! And How Much Whp Did U Get On A Shot? As Far As A Swap, I Frickin Wish! A Swap Out Here In Salt Lake Runs About 5 To 6 Grand! I Might Be Able To Push 3 Or 4, But 5 And 6k Is Way To Much For A Dad And Husband!

I had it ran in diffrent ways, origionally I ran a 50 dry shot... then swapped it over to a 75 wet shot which is much much much safer and easier to tune, then I had it set up to cool the air in the intercooler when it was turbo.

The engine, well its still runing strong.

Can someone give me a clue on what "Headers" are? I know what exhaust manifold is, I know what a flex pipe is, I know what a muffler is but im a bit confused what a "header" is. Also catback exhaust means just a certain type of exhaust correct?

header=exhaust manifold

catback means all the pipes AFTER the cat including the muffler. axleback means just the bolt-on muffler.

true, true, but how can you not know what a header is? Or a catback? He knows the other terms like exhaust manifold... How could you not know header?

Well, in my case, I bought a header for my LX. Then, I had to search around and find a defouler for the 2nd O2 sensor because I couldn't find one in my area. So, I ordered one from E-bay. Had to wait for it. Once I got it, I did a fitment and realized that the alternator and A/C lines were in the way. So, I would have had to take it to an exhaust shop to have the second O2 bung relocated. Then I decided that I didn't want to delete my cat converter afterall, so then I would have had to buy a new cat and extend my second O2 sensor wire blah, blah, blah. All of that effort and $ for what...1 or 2 hp? No thanks. I just sold it in the end. I'll wait for the Magnaflow header/cat combo for the LX if I'm still interested by that time. The issues I was talking about weren't necessarily things going wrong with the car after installing it, but rather all the bullshit trying to get it put on.
