What you hear is the end results of that sound waves final push out of the system. Once that wave makes its way into the larger portion of the exhaust which is typically the muffler it slows down again as it comes into contact with different packing materials such as BAFFLES. As exhaust leaves the combustion chamber, through the exhaust port and into the first bend or section of the piping it expands and slows, developing pulse waves of both the burnt gasses and sound waves as it makes its way down the system. Typically most standard exhaust system will have stages in the exhaust where the pipes diameter changes as its makes its way towards the end of the tailpipe. Highly sophisticated engineers develop exhaust pipes and mufflers to handle the pressure waves, noise waves as well as a process called “ scavenging” through ways such as exhaust tube size, length, and restriction points. What you are hearing is the aftermath of the contained explosion going on inside the combustion chamber.

As your engine goes through its cycles, it’s last and final stroke is called the EXHAUST stroke. Your exhaust systems main function is to get rid of the spent or burnt combustion process from the compression stroke as effectively and efficiently as possible.
