That rumbling noise coming from the engine that didn't use to be there might make your car sound good, but it's likely wreaking havoc on your engine, and possibly your health. The loud rumble is a sure sign of an exhaust leak. Exhaust leaks are dangerous because not only do they cause driveability problems but they allow for the possibility of toxic, colorless and odorless fumes to enter the passenger cabin that can quickly cause a driver to pass out and die. If you experience any of these signs of an exhaust leak make an appointment with your local auto repair mechanic right away.

Increased Engine Volume

The most telltale sign of an exhaust leak is often an increase in engine noise. As mentioned, it may make your vehicle sound good, but the noise is doing no actual favors for your vehicle. This noise will likely be louder as you accelerate. Leaks can happen anywhere in the system and even pinhole leaks can create a loud roar. An exhaust leak near the manifold can increase engine volume and it carries a great risk of allowing toxic fumes to access the passenger cabin. Any odd noises should warrant a trip to the auto shop.

Gas Pedal Vibrations

Another common symptom of an exhaust leak is a vibration sensation. If you notice the steering wheel vibrating or can feel it in the gas pedal, especially during acceleration, there is a good chance that you have a small leak somewhere in the system. The force created by gases leaking out of the exhaust pipes through small holes or cracks will cause the vehicle to vibrate.

Decreased Fuel Efficiency

One of the less common signs of an exhaust leak is a decreased fuel efficiency. An exhaust leak causes pressure issues within the engine that can cause it to burn unnecessary amounts of fuel based on oxygen sensor readings. Typically the drop in fuel efficiency will be in the 2-3 MPG range. However, a drop in MPGs related to an exhaust leak will usually be accompanied by one of the following symptoms as well. If you ever have mileage problems be sure to have them diagnosed by a mechanic.

If you suspect that you have an exhaust leak you should never wait to have it checked out, as the risk of poisonous gases entering the vehicle is very real.
