After dealing with a couple different converter manifold setups, I just wanted to reliable solution to be rid of my P0420 check engine code once and for all; and the best solution to that was to replace it with a new OEM unit.
Also, while I was in there I decided to try to fit up the full undertray splash guard that comes on the turbo models in order to keep this new manifold protected a bit better from the northeast winter road salt spray.
