i've had my Greddy Evo II exhaust installed in my car since early july.

everytime it rains outside, my exhaust will start making a loud weird rattling noise and there is vibration that sounds like its coming from under the passenger seat. my center console vibrates while it makes this noise. and this only happens when it is raining outside.

any one think they know what could be wrong?

damn this has been talked about alot.

its just the cool water sitting on hot exhaust pipe and popping until it gets dry.

There is nothing wrong with your car, and wont be dealing with this matter.

I hate to tell you, but just search around, you'll find thousands.
