When accelerating or when you’re on somewhat dented roads, you may hear a rattle of metal from your muffle, why?
WHAT IF MY SILENCER MAKES A RATTLE OF METAL ?
A loose bracket, rubber hanger or connector, or one that is badly corroded, can allow a muffler to rattle when you accelerate or drive on bumpy roads, or even when the car is stationary and idling.
A loose muffler can allow excessive movement in other components as well and increase the stress on those parts, so it can become more than an annoying noise if left unattended. If the muffler is hanging lower than normal, there’s also a risk that it could be broken off by hitting a bump or going over railroad tracks.
Modern exhaust systems are usually made of aluminized steel or stainless steel, but that doesn’t mean they or the parts that hold the exhaust components in place last forever. Heat, debris, road salt and moisture can all cause rust in the exhaust system.
A rattle or banging noise from the exhaust system might not be an external problem. Baffles or other components inside of mufflers can come loose and cause internal rattles.
Watch for this scrap noise and do not delay too much before making the repairs so as not to aggravate the situation.
