    Nothing is impossible. Take it to an exhaust shop point at the S52 exhaust manifold and the oem exhaust, and say "join that to that". And they will. And you will pay them money and everyone will be happy.

    Except you may not be happy once you realise that you were probably better putting the OEM exhaust in the bin and making a whole new exhaust to make use of your s52 POWA.

        S52 will need two cats to comply with CARB requirements for that motor.
