Because there is NO debate.
It's not like your asking which is better coke or pepsi. It's like your asking us which is a better housepet, a dog or an elephant. And just because a few guys told you an elephant, you want us to argue WHY a dog is better? Face it, having it in the DP is pointless and defeats the purpose of even having it at all. You might as well mount it after the cat. At least that way if the probe breaks off, you can pull the piece out through the muffler.
