If your vehicle is showing exhaust pipe is hanging low, loose, or dragging on the ground, here are the most likely causes and the parts you'll need to fix each one.
The rubber isolators that suspend the exhaust system under the car dry rot, stretch, or tear over time. When they fail, the exhaust loses its support and sags or drops.
Metal clamps and flanges holding the exhaust sections together are subjected to extreme heat and road salt. They eventually rust away, allowing the pipes to separate and hang down.
If the exhaust was recently replaced or removed for other repairs, the technician may have forgotten to reinstall a rubber hanger or failed to properly torque the clamps, causing the system to vibrate loose.
Severe corrosion can cause the metal exhaust pipe itself to snap in half or detach completely from the muffler or resonator, leaving a section physically dragging on the ground.
Bottoming out on a speed bump, steep driveway, or road debris can physically tear the braided exhaust flex pipe or rip the entire system off its mounting points.
