I have an 06 wrx wagon with cobb air intake spt cat-back exhaust an upgraded down-pipe, and a short throw shifter. It has 128,xxx miles on it and I am the second owner.
whenever I put the car in neutral or even just when Im not accelerating, I hear a really loud rattle coming from the car. Maybe something is loose? I dont know. It rattles as the rpms are going down. This happened out of the blue and I am just wondering if anyone knows what the issue is......any help would be greatly appreciated.
Thanks in advance for any help
