GT3 MKII Catalyst fault

[Sebsea]

My engine warning light came on the other day so i nipped in past my OPC as i just recently renewed my warranty.... turns out i have a fault in one of my cats in i think he said bank B. Sorry my car is a stunning 2003 model with 31k on her. Anyway after finding out it's not covered under the warranty they're going to call me with a price - i was just wondering if anyone else has had this problem as i find it unusual that a 4 year old car with 31k on the clock would have this problem.....? And what kind of effect will it have on the motor ?

I can't see that it would damage the motor ---- all it might do is mess up the emissions.

Why not investigate the fitting of wider cell cats in place of the originals ? These in conjunction with an appropriate exhaust and remap might give you a few extra horses --- should you want them.
