As long as they are OEM. Aftermarket won't last as long. Did you call IoS?

Why did your go bad? Did you correct the problem?

See what the warranty is on these. OEM will be alot more probably, I used aftermarket on my 300ZX and it is now 9 years and still works great. How many miles you go on your car? If you have 200k than I'd expect you'd need a new set, but if not you have something that needs attention that caused it to wear out in only 9-10 years.

yea i have also used aftermarket cats in the past, does anyone have any suggestions on what can cause the cats to go bad so early. the car has under 138,000 on the clock...

Wow only 138k, you must have something going on. BTW, how do you know that you need new cats? You not passing smog?

the service engine light came on and took the car to my mech... when he hooked it up to the code reader it read an issue with bank 1 and bank 2...left and right cat...

Are you sure you trust his diagnosis? I would suspect O2 sensors before cats. unless he told you a good reason to believe that they're actually bad.

What were the actual codes? Were they P0420?
