$$\hat{R} = R_2 + R_4 || R_1 = 6 \Omega$$
$$R_{Th} = R_3 + \hat{R} || R_5 = 8 \Omega$$

The correct answer here should be $$2 \Omega$$

From what I remember of this stuff, I agree with your answer of 8ohm. At any rate, surely it cannot be any less than R3, can it? Are you sure you are comparing to the appropriate answer?

8ohms look right to me as well.
