You may not hear a loud noise from the exhaust, a rattle from your muffler or metal parts dragging on the pavement but that doesn’t mean rust, wear and tear haven’t taken a toll. Though it’s reasonable to expect several years of reliability out of an exhaust system, vehicles should periodically be inspected for corrosion or signs of damage. This is the best way to protect your system from further potential damage.
Hangers, clamps and brackets holding exhaust parts in place can wear out, allowing excessive movement of components that accelerates excessive wear in other parts.
Your cars exhaust system and parts are subject to extreme heat and difficult road and environmental conditions that make it unlikely they’ll last a lifetime.
