Currently the fuel injector seals are being replaced. This is the last step before determining if I need a new cat.
The shop recommends a California catalytic converter but he says they are difficult to get and very expensive ($795). Does anyone know the best source to get one? He does not think a non-CA cat will reduce the NOx enough to pass the emissions test.
Is a CA cat a straight replacement or is the piping different?
