2001 Corvette G - P0420
I need a recommendation for a cat replacement.
My vette has 4 cats and is 50 state legal, so I need a cat muffler system that is 50 state legal.
1. I replaced all 4 oxygen sensors.
2. P0420 still show up.
3. GM Cat Emissions ID - 57VAGFFF
4. Can I replace just the cat related to P0420?
or
5. Replace all 4 cats.
6. Recommend a nationwide muffler shop to install it.
Thanks
