i took the cat out and it rattle like a bugger. its toast lol. took out 02 sensor and car ran fine. will check fuel pressure when i get a new cat. anyone know where to get one in calgary area that i dont have to cut my left nut off for a new one? i really dont know how the car ran with the cat melted up like that inside. how much plat and other good metal inside the cat is there. i cut it open and gutted it. can we weld it back up and use it that way or will the sensors pick up on it?
