P0420 code replacement
So the old p0420 code is on and the dealer has quoted me $1050 to replace the cat. All of the muffler shops are saying about 800. Last nite I ordered up a new cat from auto parts warehouse for $226 delivered. Looks like my sat. will be with the wrenches. I think the hardest part will be clearing the code. Unless the new cat will make it go away
