Catalytic converter

As long as it's not clogged, it will only add noise. If it's clogged back pressure will give issues out the wazoo! & it would need to be corrected asap

Re: Catalytic converter
If it's burning oil then you need to find out why or how it's burning oil, if you have blue smoke that is an internal engine issue. If its just smelling then it's most likely an oil leak onto the exhaust. That is up to you to determine how the oil is being burnt.

Re: Catalytic converter
I wouldn't put a new one in just yet, as others have said, you have to find out where you oil leak is coming from, you might clog and destroy the new one.

Re: Catalytic converter
I removed my Cat and...POWER! Felt guilty about the enviornment though so placed a high flow Cat on it and then I placed a cold air intake on it also and the difference was noticeable. I went with the short Cold Air intake and runs great.

Re: Catalytic converter
Hi everyone I'm new to this site and can not post yet but I'm in desperate need of help ! I have a 1996 civic 2 CX ...i believe the engine is a 1997 Tech ...just a couple of questions, i experiencing rattling and Oder from the cat and i know it has to be replaced but can it effect the performance of the vehicle ? It runs GREAT cold but when it warms up it dog's through low RPM...is it STILL the catalytic converter or is there something else going on there
Thanks !

Just a heads up.... You might want to post this question in one of the Civic forum catalytic converter related threads. You might get more Civic related opinions.
However, as little as I know about Civic's. I might be able to help you out a bit.
What type of odor are you getting and why do you suspect the cat?
Is your check engine light on?
A clogged cat will hurt performance. If it was wide open or you were getting a secondary O2 sensor error code. It won't always cause any significant performance issues warm or cold.
If you replace the cat and that doesn't solve the issue it could have something to do with your EGR system or an engine coolant temp sensor issue.

Hi...and thanks for the responses ...YES my engine light is on and it's smells like sulfur sometimes and you can hear a rattling sound from time to time....I'll be checking out the EGR and cooling system sensor for sure...and thanks for the advice

Re: Catalytic converter
With the CEL on, have you had the codes read from the ECU? If you have, what codes dose it have stored? If not, you should find someone who can scan them for you.
I'm not 100% but I know with my 96 Accord you can still do the self diagnostics (paperclip method) to read the CEL flashes of the stored ECU codes.
