I got 146k on the odometer, and trying to find a few more MPG. As far as I know it is the origional cat, no funny smells or anything, just wondering if its worth relpacing it.

 

ohh, by the way its all stock.

 

if its fine i would leave it

 

buy mine

 

I'm not 100% sure but I think you might have to replace it when you hear like deep, grinding sounds at the bottom of your car, usually after shifting gears. A guy I know said it's because the parts inside the cat is falling off or some **** like that and those **** can block the exhaust. Just replaced mine recently and it run way smoother afterwards. But be ready to spend a chunk if you have one of those that is part of the exhaust manifold.

 

usually when u start smelling rotten egg smell then its usually a bad cat

 

when you cant pass smog with a test pipe. cat on for smog, off for two years, back on when smog comes around.

 

they all lie. When my cat went bad the car would not go over 55mph and the entire car would shake and it would hiss like a mother.

all new rsx's CAT's smell like rotten egg's

 

If it's clogged you would know. One day the honeycomb will just break appart and you won't get it past 2500rpm. If you wish to save money some muffler places will install you a used one if you pay cash and don't ask for a receipt. Seeing as a cat lasts 7yrs or something getting a 2 year old one for a quarter of the price installed makes sense. That's what I did.

Cheers.
