The past few days I've noticed my exhaust sounding differently. When I'm in the car the sound vibrates more when I accelerate and change gears and outside it's a lot louder than usual. I recorded a video from tonight, there's no reason a stock 2002 nissan sentra gxe should sound like that. Somethings wrong and I lack mechanical knowledge to identify the problem.
