Exhaust Manifold - Please Explain

Exhaust Manifold - Please Explain
My Exhaust Manifold has been cracked on my 1998 Si for a while now. Its not too loud, but I've been driving it like that, I have a few questions:
Im getting different responses. Some people tell me just to keep on driving dont worry about it.
1) How much does a cracked manifold affect fuel consumption?
2) If I get a header, will my problem be solved? and is it worth it, cause in like a year or two Im doing a swap....hopefully
3) Somebody told me they can weld it, what about that?
4) Does the cracked manifold affect performance?
5) What about replacing it with a used manifold?...any used parts shop that u guys recommend?
Thanx for educating me

I know the letter your talking about cause I also have a 1997 DX (my mom's car) my car is a 98 SI. I got the letter for the DX and assumed it also covered my car, but the dealer said no. I thought he was just being a *****, so I called Honda Canada, they said it doesnt cover your car....I'm still perplexed!
Has anybody got this repair done on an SI?
My mom's exhaust manifold is fine...Ill probably switch the manifolds then take in hercar, get the new manifold and then switch them back!

the exhaust manifold on your SI is different from the DX'. so problems caused by mistakes in the casting procedure of the DX exhaust manifold don't necessarily apply to your SI.
(oops, I've just noticed. Desispeed drives an SI )

If I switch the manifolds will the dealer realize?
Do the manifolds look the same?

I don't think there is any difference between the CX manifold and the Si manifold, as they both are D series engines and the Si isn't a great leap towards performance either other than the added bonus of VTEC (in terms of engine specs).
I think that there shouldn't be a problem with you switching it, and even if they do notice (which I doubt), just say you bought the car like that or something, like their going to know right

I'm pretty sure they'll notice, 'coz the DX manifold has a close-coupled cat and the SI's cat is at the bottom of the car.

That is correct! The cx/dx have the cat built into the e/m, whereas the si has the cat mounted under the Car.
So to answer your question yes they will notice as they are two entirely different manifolds
