My catalytic converter has been making a terrible sound lately, and its time for a new one. It only makes the sound when its in reverse, or drive with the brakes held. Its a rattle kind of noise, maybe its clogged some. It stops when i actually get going though. Anyway I was thinking it could be a little while before i can get a new one, so should I just cut it off and replace it with a straight pipe, or would it not be worth the emissions problems?

 

if you cut it off you may have problems with you O2 sensors. the OBD2 system has a sensor behind the cat. you would have to replace it with a simulator. if you have an OBD1 like i do then you wont have any probs. it will just be louder. i had to put a cat back on my car, it was to loud for me personally

 

yo bill... you will get more rasp.

 

hmm. i was wondering about sound.. think it would sound bad at all?

 

do i really need an o2 sim though? the sensor is before the cat; or is there another one after it somewhere?

 

Magnaflow Carsound High flow cats are $50 shipped to you on ebay...

You will get an SES light if you remove the cat w/ straight pipe...i THINK it will run just fine tho

 

rasp will be a prob and an o2 sim...

 

mine was very raspy when i had the cat off. i orderd the magnaflo high flo that badinfluence speaks of. i recomend that to you. i have a much better sound given that it is still a v6

 

hmm a rattle when u put the car in reverse huh? Besides R&R the cat have u looked to make sure all the rubber boots that attach the exhaust to the car are good to go? I only say that bc i had a similiar situation occur with my 92.. so just something to check

 

yeah im just not even going to bother with taking the cat off. im just going to wait until i get a new one.. As for the rattle.. its something inside the cat. If you hit the cat with something you can hear it rattle..
