[EDIT] When I'm climbing up a hill and I rev up at high rpms I hear these popping noises from the exhaust. When the car is idling the noise goes away but when I rev up I hear a noise that sounds like poping from exhaust. I have a 99 civic ex. Anyone had the same problem or knows what could causes this noise??
