^ I thought he would know. It's just like the good-for-nothing big ass resonator that's hooked to the stock intake. Back in 2001 when I had my first camry. I took my car to Toyota and they didn't even know what it was. After 30mins the senior mechanic came out and said "I guess it's a resonator". :lol: I tell you. Those dealerships.
actually its the rear exhaust vent for air travelling through your car. On my Cam, its located at the left rear, behind the bumper.
Its job is to let air out when there is positive pressure in the cabin and to seal when pressure equalizes so no water or crap gets in.
