I drove an 06 STI tonight with turbo catback and tune 18psi.... Awesome, rode really nice and wow does that turbo spooooool. Tough to drive for the first time, but with some practice I think I am going to love it. I am only going to buy knew because the kid that let me drive it only had 8000 miles and had ragged the **** out of it and something was messed up with the steering, he said when he races he would drop the clutch at 6000rpm.... Dang, I wont be getting a used one. But its a real nice car.
