I got a Buschur hfc magnaflow setup. From the very beginning, whenever it rains and I go over a puddle, the exhaust sound gets twice as loud with slight popping noises. This continues for a few seconds and then back to normal. I've reinstalled my exhaust twice already (got a ticket). The last time the exhaust was reinstalled it got even worse... now I hear the popping noizes whenever I take hard turns. Does this make any sence at all? Why would water trigger this? Anyone else experienced this? Please advise...

backfiring? sometimes gas somewhere in the exhuast, i believe usually in the cat, is just sitting there and is ingnited causing a poppin noise, correct me if im wrong

Check for leaks, if not then maybe the hot muffler changing temps very rapidly when it gets wet.
