Loose exhaust systems often become noisy as they bang on things under the car when you are driving. The constant movement and impact against the vehicle's frame or other parts under it can damage the exhaust system in several ways. If the issue is not resolved, it could result in extensive exhaust system repair.
Exhaust System Movement
The exhaust system on your car runs from the engine manifolds to the rear of the vehicle where the tailpipe exits the body. The system has multiple components along the length of it. To keep the system in place, the exhaust system uses hangers that support it.
The exhaust hangers are typically made of rubber, and over time they can begin to deteriorate and may break. This allows movement in the system, but any exhaust system repair shop can replace the hangers for you to stop the movement in the system.
In some cases, the exhaust system repair shop may recommend replacing the factory hanger with one that is more durable to better support the exhaust system, especially if you drive on rough roads regularly.
Dents Cracks And Holes
If you have been driving your car with a loose exhaust system, things like the mufflers and the catalytic converters may have dents in them or cracks and holes from hitting things under the car. Any part of the exhaust system with a hole in it needs to be replaced because it is leaking exhaust gases under the vehicle that could get into the passenger compartment.
If you notice exhaust fumes in the car or if the exhaust has been banging and making noise for a while, take your car to an exhaust system repair shop and have them inspect the entire system for you. Many shops offer free exhaust system inspections. After looking at the exhaust pipes and components, they can help you resolve the noises and secure the exhaust under the vehicle properly.
If you find that the exhaust hangers on your car are not providing enough support for your exhaust system, you may want the tech at the exhaust system repair shop to add some additional support for you. While this is not common, it can be caused by aftermarket exhausts, high-performance systems with more significant high flow parts, and large pipes that weigh more than stock parts.
Often the simplest solution is to add several heavy-duty hangers to the system so that the parts are better supported and can not move around under the vehicle. Many different types of exhaust hangers can be used, and the tech working on your vehicle will have access to the parts so they can be added as needed.
