Does a good faith exception to the exclusionary rule apply in the absence of probable cause?

We conclude, however, that these two pieces of information taken together provided the magistrate with a substantial basis for concluding that there was criminal activity that could be uncovered in a search of the mobile home. Because we find no clear error in the magistrate's conclusion that probable cause existed for the search warrant, we need not determine whether the good faith exception to the exclusionary rule would apply in the absence of probable cause. See United States v. Leon, 468 U.S. 897, 922 (1984).
