Besides the brakes on your vehicle, one of the things that can go wrong in your vehicle is the exhaust system. The exhaust system is located at the very bottom of the engine and it is closest to the road. The exhaust system hangers, also known as exhaust supports, are the mounts that are used to secure and support the exhaust pipes to the underside of the vehicle. The exhaust hangers are usually made of rubber to absorb vibrations from the engine and to allow for flex for the exhaust to move as the vehicle travels. They play a key role in properly securing the exhaust and preventing noise and vibration in the cabin.
