After I got my exhaust, when it rains, and the cars at a low rpm a loud almost clanging sound comes from underneath the car. It sounds like it's behind the cat. The only thing we could think of was maybe when the pipes were welded maybe there's a small leak and the back compression is sucking water in. When I hit the gas, sometimes it takes a second but the noise goes away, and it only does it when it's raining.

Could someone please help me?

Thanks

man that sucks....stick ur head in there and see if u find a spot that it is really loud...then with a hand (dont touch) feel all the joints to see if its the 0 ring seal. i had a nasty sound like a stong muffler with many holes comming from my resignator..eventually i replaced it. let me know how it works out.
