Those strange silver strands coming from your car’s exhaust are likely fiberglass packing from inside the muffler.
This sound-deadening material can escape when internal components deteriorate due to corrosion, moisture, or wear.
If you notice a louder exhaust, rattling noises, or reduced engine power, your muffler may be failing or becoming clogged.
Have a mechanic inspect it soon, and avoid handling the fibers with bare hands, as fiberglass can irritate your skin.
