heat shield removal

as long as have heat shild on top

Subarus can have a lot of heat shielding on them. All heat shields ( on the bottom of exhaust system) were installed with the idea to keep other items from coming in contact with the hottest parts of the exhaust system, ie leaves or any other item you can park on top of or could pick up while driving over it. The shields on the top part of the exhaust are to keep the floor inside the car from getting hot, possibly burning. Those should be left on.
