I'm having problems with my cat getting clogged very quick. Everytime I change the cat, the car would run fine. But after a month or so, it starts going bad again. Maybe something is leaking into the cat? I was wondering if there are other s2000 owners that have this problem before.

whay do you think its going bad? CEL codes? you may just have a bad secondary O2 sensor

is the car stock? info would help

are the "old/no good" converters crushed or damaged(inside) after the incidents?

Jimbo

yea car is pretty much stock. the old cats have a rattling sound. no cel codes. its getting kind of annoying.

delete your cat.

dartonh22

if your not getting a CEL then what makes you believe the CAT is going bad?

thought the same thing about my VW(POS)...turned out to be the shit cats "vw" supplies...do you bottom out at all? you may jus be bending the heat cover toward the cat( if you ever scrape or drag)..gl

Probly just the cats heat sheild loose and hiting the cat makeing a noise. Happens alot .If this if your third cat then I would try something else obvoisoly it not the cat. Sounds like a shitty Job done or the heat sheild.

by any chance is your gas milage bad or are u having any misfires?... exessive amounts of gas due to running rich will ruin a cat very quickly
