S14 zenki exhaust questions

[sunrat]

So,

Number 4 is the catalytic converter
Number 5 is some sort of resonator?
Number 6 is some resonator as well?

I really don't need 9,10,11 and 12, correct? Only shield I would need is number 3?

If that's the case I'll just rip off those rusted shields and just put on exhaust wraps.

5 is hollow, 6 is the resonator.

Aftermarket exhausts don't have the shields. So, I think you'll be fine.

Ah ok. Thank you!

On this page it shows that number 5 is the converter. It makes sense for 5 to be a converter because number 1+4 can be combined from say, obx (they make a header that looks like it is combining 1+4) and thus you would still be able to have a cat converter at number 5.

Sorry for bringing this back up, I am just trying to make sense of it all.

On a S13 this is true. On the USDM S14 they changed the exhaust manifold and put a close coupled cat in the down pipe. This is why #4 has the big box on it by the manifold.

#5 is a hollow shell of a cat. It was easier to just make empty shells than another short pipe. Tap on it with a hammer, you will hear it's hollow.




If #4 isn't rusted and only 9+10 are then just toss 9+10.

Thanks for the info!
