Exhaust manifold
- Test the car shortly after starting it. You may be able to hear and feel the leak more easily while it is still cold
- Listen to the car. Most exhaust manifold cracks or leaks will cause a ticking noise, especially when your car is running cold. There may even be a noticeable vibration that goes along with the noise
- Use a stethoscope to listen to the manifold closely. You should be able to determine the location of the leak if there is one. If you don't have a stethoscope, use a hose or tube to localize sound
- Check your manifold physically. If you can get it out of your car and manually inspect the part, you may be able to determine warping or cracking. Since this requires removing parts from your engine
- Look for damage around the exhaust ports. Discoloration or burnt paint often signifies a leak
Catalytic converter
One of the first things an experienced mechanic will do to trace a clogged converter is they will temporarily remove the oxygen sensor or unbolt the exhaust downpipe. If engine performance improves with the sensor removed, chances are high that the catalytic converter is the component that’s causing the problem
Silencer/ muffler
Dents on the muffler or the connections can cause issues with airflow. The muffler tends to be more susceptible to rust damage as moisture can build up inside. Surface rust is normal, but if it penetrates through the metal, be sure there is more rust on the inside.
