A hole in the muffler would cause a knocking sound in your muffler. A loose exhaust pipe can also cause a knocking noise.
Exhaust gasses are escaping through a hole or rotted section of exhaust system
No, it will just make the car loud.
The cause of an exhaust indicator light in a Volkswagen Beetle is probably an oxygen sensor. There also a possibility that an exhaust pipe is plugged or there is a hole due to rust.
I had the same problem with mine. There is a metal piece in side of the exhaust pipe that can break loose and resonate (vibrate) with reving of the engine. The cheap and easy fix is to torch a small hole in the exhaust pipe and then weld the loose metal piece to wall of the exhaust pipe then weld the hole shut. Mines been good since. Please post if this is not the problem.
Fixing a leak depends on where the leak is and the severity. An exhaust connection could be loose or a gasket is bad. If there is a hole in a pipe there is a possibility that the hole can be welded, taking care to stay away from fuel lines or anything flammable.
You can drill a hole in anything as long as you have a strong enough drill bit and drill. But why would you want to drill holes in your exhaust? The exhaust piping is there to route exhaust gases away from underneath the car so they don't pool up underneath your car and seep into the cabin and cause a variety of health problems.
Radiators do not have exhaust.
One of the causes could be a hole in the exhaust
We may lose the castle if we fail to loose our arrows in a timely and accurate manner. A hole in your pocket may cause you to lose your loose change.
Yes! Then you would have triple exhaust.
If you have an O2 sensor, your O2 sensor will not read exhaust gases properly which may cause the ECU to make the engine run rich. Yes. Holes close to the engine in the headers may also cause unburned fuel to ignite in the headers causing backfiring.
