What to do if a clamp comes off muffler?

If a clamp comes off the muffler, first ensure the vehicle is parked safely and the engine is turned off. Inspect the muffler and the exhaust pipe for damage or rust, then reattach the clamp securely, tightening it with a wrench. If the clamp is damaged or missing, replace it with a new one suitable for your vehicle. If you're unsure or the issue seems complex, consider seeking professional assistance from a mechanic.
