I have a 1997 M44 318ti. in the past 5 months I have noticed that when ever it rains, if I drive through a puddle my exhaust gets EXTREMELY loud. I have a stock exhaust that isn't loud by any means but as soon as I hit a puddle *BOOM* I sound like a riced out Honda Civic with a coffee can strapped to my engine. any thoughts on what this might be?

Could be a crack in the exhaust expanding or contracting from the temp change.
