Rep Power: 0 Cracked Manifold help
Manifild has a crack right next to 02 sensor and i was told to buy a new one online cuz it would be cheaper. A coworker told to get a 4-2-1 header. I was goin to do it but noticed that i would have to remove my catalityc converter and have to live with the engine liggt on. Do i need to have the cataliryc and 02 sensors? is it bad if i dont?
Should i just buy the 4-2-1 header or look for a stock manifold?
Dont really know muxh about cars and wanted to know what other people thought

$60 Header (1999 Honda Civic Bolton Premiere Headers) (Part # REPH961301)

Stay away from cheap no-name headers. A quality one will have a port for the O2 sensor. I'm guessing your Civic is the one that has the cat right attached to the manifold. You can buy a new cat, and have it welded on under the car after the header.
DC Sports and Pacesetter make decent quality headers that aren't too expensive.

Re: Cracked Manifold help
Legally, yes you do need a catalytic converter... especially if you have to go through emissions testing in your state. It helps reduce harmful emissions into the atmosphere. The upstream (header-mounted) O2 sensor allows your engine to make adjustments to run more efficiently. *Definitely Important!* The downstream sensor (located behind the cat) is used to measure the efficiency of the cat system, and to my knowledge is only really used by emissions testers.
Your LX has the converter attached to the exhaust header so unfortunately it'll be a more expensive part to replace. If you were planning on upgrading your exhaust anyway, you could change to the EX system (which has your catalytic converter located under the vehicle after the header). This would give you a better choice on exhaust manifolds.
I would not recommend driving without a cat. Just my .02

What do you guys think about me buying the header and getting O2 extenders / defoulers?
Bad idea?

Here's an EX-type catalytic: http://crazyboyauto.com/magnaflow-19...nverter-22630/
I personally wouldn't do that, although I would consider getting the high-flow cat for a potential performance gain. If my existing converter went out, that is.
