Catalytic Converter for 98 lude
I have a 98 lude and the cat has seen better days. I say that cause my CEL is on and the code is 67 which says either bad O2 sensor or bad cat. I replaced the O2 sensor, reset the ECU and the light still came back on. And the exhaust is making a loud rattling noise suggesting the cat.
My question is: is it worth it to get an aftermarket cat? I am really looking for a bolt on (not welding) that can still pass California emissions. What brands are good that meet this criteria?

go with a carsound cat. You will gain hp and you will pass emissions or so i have been told. www.kteller.com you can pick them up there. Just let them know what car you got and they will fix it up for you.

if you have a 98, there are 2 o2 sensors. maybe look into replacing the other one. then clear the codes and see if it comes back. if it comes back again, there is something ilse wrong. you could have a short or an open in a wire. i dont think thats the case tho.

well I've been told that if the cat is making a rattling noise, that means that the inside material is loose and its in need of replacment. And last night it was really loud in low rpm.

Thanks, I checked out the website and it looks good. I sent an email asking about a cat for my lude. Hopefully the will hook me up.

he tends to have VERY good customer service. But since it is the weekend i would give him atleast a couple days during the week before you expect a response.

Best bet, is to change out the cat, then go from there

On the 5th gen there are 2 O2 sensors, one before the cat and one after the cat. It might be because its OBD II.
