DIC showing code P0420. Might need new cats so just checking to see whats out there. I have a 2000 c5 coupe with 98,000 miles and with B&B bullet mufflers. Have the original black calipers that I took off around 60,000 miles and stock rotors to trade if interested. The front rotors have under 10,000 miles not sure about rear rotors. Bought the car with 43,000 miles. Would like cats off a low mileage newer vette if used. Thanks, Phil
