Part #: 44059AA030
When removing or replacing exhaust components, it is always a good idea to replace gaskets, as well as the bolts. These parts endure a lot of heat cycling and eventually after a certain mileage things can get stubborn, and just become a pain in the butt to remove.
These are Subaru OEM which means they will thread in correctly the first time.
