Recently my catalytic converter started to smell somewhat bad.Contacted the 4 wheel drive place where i get most of my work done and was told that they can only put the OEM cat back on the vehicle.2 years ago this was not the case.They said it is a $15,000.00 fine if they put on an after market cat.Does this sound right? Also they said the cat goes for $580.00 not including labor.Are my getting fed a line of bull?Please someone.Thank You.Also should i try the O 2 sensor to see if that is fried?Wouldn't that cause the cat to break down.So far no check engine light.Thank God!

I would suggest just doing it yourself all you need is an angle grinder and a few wrenches. Magnaflow cat from Summit $115 shipped to your door. My .02
