Whats the Best O2 Sims? and Where can i get them

[Ironranger30]

Hey guys i just bought a 2003 Z06. love the car but it throws a Check engine light every now and then because of a cat Convertors. Dealer thinks they are carboned up/plugged. Car has 65,000 miles. I am gonna cut the cats out but where can i get )2 Sims that actually will work.

thanks a lot guys.

Why don't you run some tests and see if the cats are actually bad or if the rear O2s are just faulty?

At 65000 miles it would be unusual to have failed cats unless the engine has been run on: gas with MMT-based octane booster, leaded gas or extremely rich mixture.
