Cat - Ceramic Vs Metal?

[jcooke]

Hey guys n girls,

Booked the T in to get the exhaust rattle checked out (wasn't rubbing against the car, was "inside" something). I'm told that one of the cat's has collapsed for sure (they are checking out the other one and the rear muffler). Now the cat I am told is a ceramic one, and I'm told that a metal one should last longer (320rwkw). Whats the difference? If the second one is ok, is there any point replacing it? I havn't had any noticable power drops as read in other posts. I was quoted $300 for a metal cat, sound about right? Car is at a repuatble repairer, not a dodgey joes.

Other little question is about warranty. The exhaust is 2 years old on the 20th may. Complete system was done by them from what I know (previous owner had done). They are kinding pushing back saying that a car of that power, warranty is a bit of a greay area. Invoice doesn't say warranty period anywhere but they have confirmed verbally 2 years.

Your thoughts on both topics?

If you got 2 years from it then I wouldnt stress... a metal cat should be fine, can't see why not

thanks man.

Update : I have now been advised that they have inspected the cat closer and it, and the other one is fine. The rattle was confirmed where I thought it was, the rear muffler, which they said they could easily repair and refit, all under warranty. Just saved me $300 odd bux plus labour, hooray.
