I have a 97 civic cx hatch with the cat in front of the engine. I was wondering if anyone has done a conversion to a regular header and relocated the cat to under the car. If so could I do it for a reasonable cost (possibly ebay parts) with little to no custom fabrication?

i want to know to.. people said to just get a d16 header

I've done this. Get a regular header for a D16. You can install the header with no problems.

Buy a cat from an EX or SI. You will have to take the cat to a muffler shop and have them weld a flange onto your exisitng exhaust to mount to the downstream flange of the cat.

You're done.

******, if you had a coupe DX and were to buy a complete exhaust system (header back) for an EX would it all bolt right up?

You have the new header, cat, and exhaust system.

Let me restate this to make sure I understand what's going on. You have a DX. If you have an EX catback exhaust, an aftermarket header for d-series(or stock EX header), and a EX/SI catalytic converter, then yes it will all bolt up fine.

Thanks a lot. That's what I thought, but I wasn't 100%. I don't want to be giving the wrong information when threads like this roll around.

what about the 93 cx?
is it the same because my cat is on front where the header is

you can just buy an aftermarket header and drive without a cat, and when you get smogged, just bolt the stock one back on. But that is not very lawful

robert_v

yea what 97 spoon civic says.

its not very lawful but there is a difference in the way the car picks up.
