Picked up 2009 WRX, grey, 4 door minus premium package last week. Almost immediately had short throw shifter installed, what a difference! This car is astonishingly fast, it builds speed at an incredible rate with minimal lag. Last thing to sort out, its way too quiet. I am looking at the Subaru exhaust, little pricey but I hope it gives me a nice, low end sound, not obnoxious, just enough to make shifting easier. Anyone have experience with this system? I feel an addiction coming on.
