Why does my exhaust sound like popcorn?
What causes engine popping? If your engine is getting more fuel than it needs, a rich fuel to air ratio is the result. When your car has leftover fuel in the exhaust and the cylinders, that fuel explosively burns and creates a loud popping sound. Specifically, here we mean delayed timing, which causes the backfire.
Why is my engine crackling?
Most likely, the crackling noise is caused by the rapid cooling of thin sheet metal heat-shields that are located around exhaust components. While all parts of the engine cool down, heat sheids are the extreme because of the very high temp they see, and because they are thin, they cool rapidly.
Why does my car sound like a train chugging?

Why does my car make popping noises when I turn it off?
As you drive, they heat up quite a bit. When you shut the car down, they begin to cool. The ticking noise is produced by the various parts returning to their normal size. Most of the ones you hear are thin pieces, like heat shields, which can change shape rapidly due to their construction and so make an audible noise.

What would a rattling noise in the engine be?
Detonation, Pre-ignition (Pinging) Noise Most people call this a pinging or rattling sound. This noise is caused by an air/fuel mixture in the engine cylinder being ignited prematurely by the heat of compression as the piston is moving up on the compression stroke.
What makes a popcorn popping sound at 50 mph?
