Before when I was running NA Subies only, I heard of WRXs and espcially Stage 2 WRXs thinking "zomg, so fast!!!111".
Now after owning one at Stage 2 (Cobb intake + turboback + AP), they're quick, don't get me wrong, but it leaves you wanting more power almost. It's kinda of once you start getting used to it.
None the less, the sound is great and the entire car stimulates your senses... noise, power, handing, visuals.
