My 04 Sedan was unfortunately towed the other day. As soon as a started it at the tow yard i noticed that the exhaust sounded louder. I'm pretty sure that it is only the muffler but I am not sure. Has anyone had had issues with the 2004 stock exhaust system? If so how much can i expect to pay get it repaired?

 

Check if you have a hole in the muffler, that usually tends to give the sedans a louder sounding exhaust.
