I need to replace the cats on a 1980 308gtsi. All the applications I see appear to be for a carb car, not injected with air pipes and thermocouples. Heck, even CARB (it's a California car) insists I need a cat without the air pipe provision. I'm absolutely certain that if I eliminate the air pipes and use what they recommend, it'll open up a new can of worms. Arrrrrgh. Who makes catalytic converters for this car????
