my question is how come they dont make headers for automatic? everything is for ex manual. im not expecting it to be a big gain just something to do with the car.. for fun. thanks for any help on this

ok, first off, not to be a dick, but we only have one "header". Headers refers to multiple. I am pretty sure they make a header for automatic trannys. I know the DC Sports and the HP header will fit, but I think you might have to trim something. Look at Dezod.com or Truehonda.com

stock header gives the best performance, since the runners are exactly port matched to the head. larger runners = slower gas flow and power loss. if you want a header just for the sake of having one, get the dc sports. same diameter pipes as stock, and it looks nice. i actually got mine jet coated (jet-hot.com) so it keeps heat in better and out of the engine bay.

oh haha my bad about the " header-S". wow i didnt u would lose power. my friend brother in law got a dc header laying in the garage from his em2.
(hella rice) so i was thinking about putting it on. whats the difference between 4-2-1 and 4 to 1

4-2-1 tends to flow better than the 4-1 because it tends to help blend the exhaust pulse better instead of just dumping it from 4 all into one.

4-2-1 vs 4-1

4-2-1
Four exhaust ports on the head that each have their own pipe (this is the "4") that come together and dump into just two pipes (this is the "2") that dump into one pipe (this is the 1) that connects up to the next section of exhaust piping. These are usually dubbed as race headers because they eliminate the cat due to the extra long piping.

4-1
Four exhaust ports on the head that each have their own pipe (this is the "4") that all come together and dump into one pipe (this is the "1") that connect up to the cat converter.

i see, my friend bro in law got a dc header laying around. should i put it on? would i feel any gain or its going to be worse. hahah.

Just throw it on, and see. Your stock header could have a lot of carbon build up on the inside that is restricting the outflow compared to the outflow of the dc header your buddy has. If it isnt worth it, then just switch it back- you really dont have anything to loose- changing a header isnt very complicated.

there is no real gain or diff feeling...

some guy on the socal forum is selling his for like 75bucks i think...the dc one.

i dont have any experience with header. especially i have a LX, i dont want to mess with the CAT.

But from what i heard, DC header is the only header for our car that smooth out the power band. Ther others just shift the power to the top end.

My megan header smoothed out my power band and shifted lower so it was more usable.
it moved the power band to 3000-4000 rpm

hm let me snap a picture of the header and show u guys. he got some other pipe with it. iono what is .. so ill get some pictures up soon

colourwolf

some pipe with it?

I guess you have a DC 4-2-1 header....
And it will elimilate the CAT.....

but ya.....post pics....so everyone can see

mrbanhbao

hey okay sorry it took me so long but here are the pictures. it look like this. couldnt find time to go to his house to snap the pictures. found these on the forum. these came off a EX .. would it work with my LX (auto)

nope wont work. unless you convert the whole rest of the exhaust system and cat to the ex setup.

mrbanhbao

oh i see...would it work if i change my whole system to an aftermarket .. like HKS and such?
