Codes P0420 & P0430
I have been told it was the catalytic converter however i was suggested to check other things ( vacuum leaks etc) that could be causing this code.
What are some things to replace before i change the cat?
If my last option is to change the cats, should i get a straight pipe instead?

On your '08 Z, cats are warranted 8 yrs. / 80k miles. Check with your dealer service dep't. Heads-up, they may want to replace sensors first.
