I just got my 06 wrx 3 weeks ago yesterday, and since then i changed out the wheels did the sti trunk swap and debaged it, new infinity component speakers front and rear.
I ordered a invidia non catted dp and hks hi power exhaust, wilwood big brake kits front and rear.
I had a cobb power pack on it with a catted dp and exhaust and access port stage 2 tune, but i sold the exhaust and dp to get the new tbe and brakes.
My buddy daniel refred me, another buddy that lives local and he is on here as well. Idk his screen name. Maybe he will chime in soon
