anyone want to guess why?

 

Do you happen to have R/T Cats?

 

that i do

 

another track day coming up?

 

Did your cats crap out on you too? (I read another thread with the same thing happening to another forum member.)

 

Uh oh- did yours fall apart too? Or just buying test pipes to hope to avoid it?

 

i guess i'm not 100% sure what's going on just yet, but basically i pulled an o2 and the shielding was dented.... so i reached in and felt what was probably the innards of the cats moving around inside.

I haven't had time to look into it further.

 

crap- not good. Keep me informed of the status- hope mine are not next. I have about 10K miles on mine and haven't noticed any problems.....yet.

 

I was thinking about getting some......is this an on going problem with them???

 

i guess i'm a little biased given my situation.... i definitely think that it is something to think about. As you can see in this thread, my riddle was not very difficult to solve. So yeah, it is not uncommon. But you also have to consider the other people who bought them and who haven't had problems. It seems that there are still a whole lot more of them than there are of us.

 

btw, i'll probably have the issue sorted all out this weekend so I'll update then....

 

Thanks for the input.

 

True that there are many people running the RT cats. But there have been a disturbing amount of people who have had the same problem.
George- did you purchase your cats as soon as they came out- or a few months after? I'm particularly concerned about mine since I bought them right away.

 

i got them just before that december trackday....

 

like a week before... so, early december 03...

 

hmmm I wonder if it was a bad batch? It would be interesting to see if the purchase dates are similar for the problematic cats.

I've seen a few post where the cats fall apart in less than 2000 miles. I've had mine on for ~12,000 (inc 2 track days) and no problems thus far. BTW mine were purchased in Oct.

 

i just crossthreaded three bolt on my exhaust.... =\\\\

guess it's time to upgrade the hoses get some carbide... which will probably rule out that track day in june....

 

Ok, I got the cats off and here are the pics...

Basically both cats were screwed but the left bank (seen in all the pictures) is much worse. The o2 looks hurt but I wonder if it's okay to use. Hilltop Nissan quoted me 170$ per sensor. (kragen, napa, and the like don't have it listed yet) The right bank sensor looks unscathed. So I might just get one.... or none? Any suggestions on that?

 

oh btw... the third and fourth pics in the gallery, are of what dented the o2 sensor...

hehe... it almost looks like it melted...

 

That looks bad!!
