What are the signs of a failing muffler?

Top Signs of Muffler Failure

• Noisy. The high volume could be a result of an exhaust leak that is stemming from your muffler.
• Worsening Gas Mileage. Issues with your muffler and exhaust system can cause your engine to work harder, which results in the burning of more gasoline.
• Misfiring.
• Condensation from Exhaust Pipes.

What causes exhaust system failure?

The exhaust system can become damaged due to various problems, which can be grouped into three different categories: rust, vibrations and incorrect use. All three categories will eventually generate failure of the exhaust system components by creating backpressure problems.

Can a bad exhaust damage your engine?

Loss of Engine Performance — If the pipes in the exhaust system become damaged or corroded, they can sometimes produce an exhaust leak that can cause the vehicle to experience performance issues, such as a decrease in power, acceleration, and fuel efficiency due to the loss of backpressure.

How much does it cost to fix exhaust?

Expect to pay anywhere from $125-$300 for labor costs. The parts aren’t going to cost much either. While different vehicles require parts of differing prices, the range is somewhere between $15 and $50.

Is there a problem with my exhaust?

You’ll know that you have a problem with your silencer because your exhaust starts making a loud roaring noise. Other noises to listen out for include hissing, which indicates a crack in the exhaust manifold, exhaust pipe or a leaking gasket. A chugging noise could mean a blockage in the exhaust system.

Does a blowing exhaust affect fuel economy?

If your car’s exhaust has a leak, this will have an impact on the pressure in the exhaust system, reducing fuel economy and leading to higher emissions. If a leak develops in the exhaust close to the engine, this can have a big impact on fuel economy, and could lead to fuel wastage.

Is a leaking exhaust an MOT failure?

Exhausts will only fail an MOT if there’s a major leak, or emissions are deemed unsafe. So long as there is no major leak of exhaust gases, or a part of the catalytic converter or diesel particulate filter is missing, your car should get through the test.

Can you still drive with a blown exhaust?

While you can technically drive with a broken exhaust, it’s neither safe nor legal and poses a number of issues when you’re out on the road. Whether your exhaust is simply cracked, is partially hanging off or has fallen off completely, it’s an important part of your vehicle which needs your immediate attention.
