My 2000 SE starts to smell fowl like eggs at high speed/RPM. Im assuming cats are bad? Should I just order new front and rear ones or if I take somewhere would they be able to determine which is bad? Car seems to have lost power as well. Any thoughts? Thanks.

 

Clogged cat, for sure. If you're losing power, I'd have diaged as soon as possible. That means the cat is almost completely stopped up.

If you're not throwing a code, it sounds to me like it may be the secondary cat. But a shop can very easily find out in a few hours' time.

 

Thanks man. Yea just seems to not have its normal pep. I will take it to my mechanic and have him replace. Should I just order both cats while im at it? I guess it wouldnt hurt.

 

There are three cats on the car. I'd say have him figure out which cat it is before you order the part...most places (Autzone, etc) can have the part within 24 hours.

It'll save you a lot of time and frustration of trying to return the other cats that you don't need.

 

You sure it's not your passenger losing bowel control when you hit redline in 4th gear?

 

 

Yea i guess that would be the smart thing to do with christmas coming up. I better not spend more money if i dont need to. Thanks again.

I would just get headers if its the pre-cats besides spending all that money on some pre-cats. Just my opinion though

 

If I was to get headers that would in turn eliminate the pre-cats? That doesn't seem like a bad idea.

 

Yes they will eliminate the pre-cats, Im just saying if you going to spend whatever for precats, go ahead and upgrade.....

 

Hell yeah and more power a win win if your in a good smog state Cali is a b1tch.
