d16y7? sohc and headers?
 

I have heard mixed things about throwing some headers on my y7. Everyone says I/H/E for all cars. Well, I have the intake and the cat-back exhaust, but I have no headers or high/flow cat...

first off, will it fit or do I have to upgrade my pipes?

second off, will it actually take away power overall? Its understandable maybe a little less low-end because it will be flowing pretty heavy, but what about top end?

Then why bother spending money now on parts that you won't be able to re use later.

I don't think there is a header available for the Y7 motor because the cat is part of the OEM exhaust manifold. A Y8 header would probably work, but then you'd also need a new cat and midpipe.

An aftermarket header will work, you just have to put an aftermarket hi-flow cat after the header.

that's what i was thinking, if your saving for your GSR swap, dont' waste your money :thumbup:

If you're going with a GSR swap anyways, why waste money on I/H/E when you can put that towards the GSR swap fund?

NOOOOO!!!!! :eek: :eek: :eek: :eek: :eek:

You damn right! :p

you should build the bottom end first, then toss it out and get a swap.

^^ you just bent your valves bud

Y8 exhaust manifold will do some tricks, but that's on a budget.

DC makes header for D16 engines. SMSP (one of the best custom header builder in the States, Dave I believe) just came out with a D16 header design. His B series headers is over 1000 USD so I think D series will be in the same area.

I dont get it, so the Y7 and Y8 have different exhaust systems?

yup!

They Y7 has it's catalytic converter built into the exhaust manifold (header);

While the Y8 has it's catalytic converter under the car, and has the normal lookin exhaust manifold/front pipe (header) up front.

Hope that helps! :)

So can I use a Y8 header and cat on a Y7 engine?

Yes you can.
But your car won't have a cat on it however.
BTW I've got a y8 manifold for sale if interested.

ok, so my understanding is that my stock exhaust manifold is integrated with my stock catalytic converter. Now, if I get headers and a hi-flo cat then I assume I am relocating my cat somewhere underneath the car. (btw... 96 hatch).

Will it stick out more (ground clearance is important as I have a lowered car of course.

depends on what cat you get and who puts it in. some places will tuck it up nice and high out of the way. if I were you, I'd try to source the whole Y8 exhaust from the header back to the cat, then go aftermarket cat-back from there. that'll give you stock-like clearance under the car, and prolly be about the same price, but with quality OEM parts in the places where it counts.

well i have an Apex WS catback system already. I just want headers on my CX. So I have nothing to choose from?

I have a World Sport and it's for a Y8 engine. I have headers and a high flow cat and then the cat-back. It fits, but the guy who installed it said it was a b!tch to do. I will be reinstalling these parts on my new car myself, so I'll tell you how easily they go together when I do so.

But the way I see it is: If the header is for a Y8, the Cat is for a Y8, and the Cat-Back is for a Y8 then, when combined, they will fit any 96-00 Honda Civic coupe or Sedan.

EDIT: You have a snatchback, so I don't know how valid my points are. Hatchback chassis are shorter. If your Apex'i exhaust is for a hatchback, then I think you may have problems with the length of the mid pipe when you go to install the headers and cat.

Oh, and I hit quote instead of edit by accident.
