Hey guys, I have a similar problem with rain...
The faster I drive, the harder it rains. I'm serious. It's like I control the rain cloud with my gas pedal. I have to click my wipers to a faster speed the faster I go.
It's crazy. Seems to happen in my other car, too, so maybe there's something defective with both of them. Do I need a new windshield? I hope its not the engine going bad.

multiple reasons, the most significant one (in my opinion at least) would have to be..;
rain droplets- as the sound waves travel away from the source, rain droplets in the air refract some of the waves back away resulting in hearing something better than when its not raining as more of the sound wave is being reflected back towards you. the heavier the downpour, the more droplets, the more sound you will hear. (this concept can be observed when comparing a noise in a open field and then again at the same volume in a enclosed environment like a bedroom or inside your car. the waves will hit the walls and come back creating the illusion of it being louder)
hope that makes sense and helps
edit: nevermind, saw a super thread revival.. lol

8 maniac I feel your pain trying to explain this to people. What I think it is, is that when you hit a deep enough puddle for the water to reach the exhaust manifold it cools the thinner exhaust pipe but not the thicker metal of the manifold, causing a small leak where they are connected. Then, after the pipe heats back up and expands, it seals the leak and the sound goes back to normal.

I wonder if I let the car come up to temperature on a dry day, and then hit the exhaust pipes with a hose, if I can replicate the effects. Maybe this weekend if the rain lets up, I'll try it out.
