I would wait until it cools off and take a good look under the car and see if you can see any damage - cat's are up near the front just where the pipes come down under the car from the engine.

Will do... I'll drop it by the shop to see what they say

Thanks Ard for the headsup. I actually bought a OBDII scanner and resetted the code. I'll wait to see how long it will before it pops back up
