Symptoms

Exhaust Abnormally Loud

Abnormally loud noises from the exhaust come from a defect in the muffler. If the sound is louder than before, the muffler baffles may be broken and prevent the engine noise from dampening.

Muffler Makes a Rattling Noise

Aside from a foreign object in the muffler, a broken baffle can slide around inside the muffler and produce a rattling noise.
