Happy 45 * 45

Here's a difficult puzzle for the new year. Have fun!
Normal sudoku rules apply.
Killer Products: Digits do not repeat within each cage. Every cage in the grid with a clue has a counterpart in the grid without a clue. Each unclued cage is used exactly once by exactly one clued cage. A clue in a cage is the product of its cage total (sum of the digits in the cage) and the cage total of its counterpart. It is up to the solver to determine which clued cages correspond to which unclued cages.
Solution code: Digits in the 2025 cage in row-major order (left to right then top to bottom, starting with r3c5)
