VF46 same as mine unless it has been converted. I believe the pre-facelift (pre-MY07 I believe) are twin scroll matched with the 2lt, not 2.5. Happy to be corrected. Either way the turbo packs some perky street punch and the VF52 off MY10/11 rexes is a bolt on upgrade (same as the VF48 from STI but this one has no flange on the comp outlet so needs a hose).
Your wagon looks the goods and that engine cover is unique, I like it a lot
