Whether you have a sedan or a 4×4 vehicle with a standard exhaust system or a performance exhaust, its operation depends on how well you have maintained and cared for it. A failing and damaged exhaust system will impact your car’s performance, its fuel efficiency as well its tone or sound. The muffler is a crucial component of the exhaust system, and something that affects the exhaust affects the muffler and vice versa.
There are many different reasons why a muffler would breakdown, and it’s essential to be aware of the signs so you can get your car to an auto repair shop on time. The experts will inspect the system, determine what the root cause of the problem is and fix it quickly and efficiently.
1. Muffler Makes Excessive Noise
This is undoubtedly one of the most apparent indicators of problems with the muffler and the exhaust system. If you notice that there is some change in the exhaust’s tone, cracks in the pipe, a leak in the manifold gasket, or a rusted muffler, maybe the cause. If any aspect of the exhaust system is compromised, you will hear a loud, growling sound. This is something you cannot ignore because it will affect your vehicle’s performance as well as its fuel economy. Also, you may have to pay a fine if the muffler makes an excessively loud sound.
2. A Drop in Fuel Economy
If you have noticed a drop in fuel economy, it is a visible sign of a problem with the exhaust. It means the system is underperforming. When the muffler or any other component of your exhaust system fails, the engine strains to work harder, which means it burns more fuel.
3. Reduced Acceleration
When you need to plant your foot further down while accelerating, to extract more power from the motor, it indicates that you have a failing exhaust system. The muffler may have become corroded, or there may be a leak somewhere in the system, that is causing this problem.
4. Knocking or Banging Sound Under the Vehicle
If you hear knocking or banging sounds beneath your car, the muffler mount may have come loose. In some cases, a cracked or broken pipe may cause this problem as well. If the tailpipe or the muffler is dragging along the ground, it’s obvious there is a severe problem. You would need to get it fixed at an auto repair shop without delay. In case you find that the muffler is coming off the mount very frequently, the mount itself and the fasteners would need replacement.
5. Rust and Corrosion
Condensation buildup in the muffler and tailpipe can cause corrosion and rust. Every time you run the car, all its components heat up. When you park the car, and it cools down, it attracts moisture; this results in the buildup of condensation. Over time, the entire muffler and tailpipe can rust out entirely. If you notice excessive condensation and any signs of rust, it means the muffler is on its last legs. Do not wait until the entire exhaust falls apart. Take your car to an auto repair shop and have the problem fixed on time.
6. Exhaust Pipe is Hanging Very Low
If you notice that the muffler and tailpipe are hanging far lower to the ground than usual, there are many different reasons for this. An exhaust mount may have failed, or a pipe may have become bent or damaged.
If your muffler or other parts of the exhaust system are showing any of the above signs, get them checked on an urgent basis at a credible auto repair shop.
