Symptoms of a Bad or Faulty Exhaust Mount

Common signs include an exhaust pipe that feels loose or wobbly, the muffler hangs to the ground, and the exhaust sounds louder than usual.

Under your vehicle are several series of different systems that keep your vehicle in good working order, including the exhaust system, which connects the metal brackets on the exhaust pipe and muffler to the chassis with very thick rubber dampers. This exhaust support or exhaust system hanger pulls together all parts related to the exhaust system and keeps them close and tight to the vehicle to avoid damaging them.

Vibration in this area of ​​the car can be enormous, and the close proximity to the ground provides ample opportunity for road debris to jump up and try to knock the exhaust system out of place next to the engine. The exhaust system mounts are made of more flexible rubber rather than solid steel, allowing the exhaust to move with the car while also providing some cushioning from road bumps.

Along with noise reduction, exhaust system mounts protect the exhaust pipe and exhaust system structure from damage, making this an important part of a quick repair. Here are some common symptoms that indicate bad exhaust system mounts:

1. Exhaust pipe loose or wobbly

Any time your exhaust pipe or pipe hangs low or seems to wobble under your car, it's time to check your exhaust system mounts to make sure they're still working. They may only need to be adjusted, so contact a qualified technician.

2. Silencer hanging on the ground

The muffler that is literally dragging the ground is one that has had its exhaust mount completely blown off—perhaps even completely ripped away from the car. In any case, check the muffler soon.

3. Exhaust is louder than usual

There are several reasons why your exhaust might be louder than usual, but the shaking and movement of your exhaust pipe when a prop fails is one possible reason to look into.

While exhaust system mounts are not part of regular maintenance, if you find the need to replace exhaust system mounts, it is a good idea to replace exhaust system mounts as well.
