Understanding the Role of an Exhaust Hanger
The function of an exhaust hanger
An exhaust hanger is a component of a vehicle’s exhaust system that is responsible for holding and supporting the exhaust system in place. It is typically made of durable materials such as rubber, stainless steel, or aluminum. Its main function is to keep the exhaust system securely attached to the vehicle’s undercarriage, while also allowing some flexibility for natural movement and vibration of the exhaust system.
Why vehicles have an exhaust hanger
Vehicles have exhaust hangers primarily to ensure that the exhaust system remains stable and properly aligned. Without the support of hangers, the weight of the exhaust system could cause it to sag or come into contact with other parts of the vehicle, leading to potential damage and decreased performance. The hangers also help to absorb and dampen vibrations caused by the engine and exhaust system, preventing excessive noise and reducing stress on other exhaust components.
Types of Exhaust Hangers

Additionally, they provide a sleek and aesthetic appeal to the overall look of the exhaust system.
Common Reasons for Exhaust Hanger Damage
Impact and collision
One of the most common reasons for exhaust hanger damage is impact or collision. When a vehicle hits a speed bump, a pothole, or any other obstacle on the road, the exhaust system can be momentarily jolted or forcefully struck. This sudden impact can cause the hangers to become dislodged, bent, or even break. Likewise, accidents or collisions can result in severe damage to the exhaust hangers.
Rust and corrosion
Exhaust hangers, especially those made of steel, are susceptible to rust and corrosion over time. Exposure to moisture, road salt, and other corrosive elements can cause the hangers to weaken and deteriorate. Rust formation can lead to structural instability and eventual failure of the hangers. Regular maintenance and proper coating or treatment of the hangers can help prevent rust and corrosion-related damage.
Degradation of the rubber hanger
Rubber exhaust hangers, although durable, can degrade over time due to prolonged exposure to high temperatures and constant movement. As the rubber deteriorates, it loses its elasticity and ability to absorb vibrations effectively. This can result in the exhaust system becoming loose, causing abnormal movement and potentially leading to further damage or failure of the hangers.
Excessive vibration or movement
Exhaust systems naturally generate vibrations and movement as a result of the engine’s operation. However, excessive vibration or movement can put stress on the hangers and cause them to weaken or break. This can occur due to issues such as engine misfires, faulty engine mounts, or worn-out exhaust system components. Regular inspection and maintenance of the vehicle can help identify and address any issues contributing to excessive vibrations.
Identifying a Broken Exhaust Hanger
Unusual noises
One of the key indicators of a broken exhaust hanger is the presence of unusual noises coming from the vehicle’s exhaust system. These noises can range from rattling, banging, or clunking sounds, particularly when driving over bumps or rough roads. The broken hanger may cause the exhaust system to come into contact with other parts of the vehicle, resulting in these abnormal noises.
Abnormal movement in the exhaust system
A broken exhaust hanger can also cause the exhaust system to move in an irregular manner. If you notice excessive swaying, sagging, or hanging of the exhaust system, it may be an indication that one or more hangers are damaged or detached. This abnormal movement can potentially lead to further stress on the exhaust system components and even result in complete detachment of the exhaust system.
Visible damage or rust on the hanger
Inspecting the exhaust hangers visually can also help identify any damage or rust. A broken hanger may appear bent or detached from its mounting points. Additionally, rust or corrosion on the hangers can indicate weakened structural integrity. It is important to regularly inspect the exhaust hangers to catch any signs of damage early on and prevent further issues.
The Dangers of Ignoring a Broken Exhaust Hanger
Potential for system-wide exhaust damage
Ignoring a broken exhaust hanger can have severe consequences for the entire exhaust system. A loose or unsupported exhaust system is more susceptible to excessive movement, which can cause damage to other exhaust components such as pipes, mufflers, and catalytic converters. This can result in costly repairs and compromises the overall performance and efficiency of the vehicle’s exhaust system.
Increased safety hazards while driving
A broken exhaust hanger poses safety hazards while driving.
