I have a 2002 Altima, it sounds like I have a hole in my muffler. The sound actually gets louder when I put it into drive. Does anyone have any ideas of what is wrong? Thanks in advance for any help!

 

Have you had all of your recalls and TSB's checked by the dealership? If you haven't, let me be the first to suggest it. The 3rd Gens had some serious problems with exhaust systems. If you have had these done, are you getting any SES lights?
