Understanding the basics of exhaust popping

Let's examine what truly transpires when your exhaust pops. Unburned fuel combines with air inside the chambers of an internal combustion engine to ignite. This causes hot gases to escape through the exhaust system which helps reduce emissions and noise levels. If these gases are not allowed to fully burn off before exiting the exhaust system then they can create 'pops' or 'crackles'.

Some tips to make your car exhaust sound louder and louder

Get an aftermarket catalytic converter (de-cat). Removing the stock catalytic converter from your exhaust system will make it much easier for unburnt fuel and air to escape, allowing for more pops and crackles as a result.
Increase back pressure by using a larger diameter muffler/resonator on your exhaust system. A larger diameter pipe will help create a higher rate of back pressure in the system, allowing more air and fuel to be forced out of the pipe.
Install stainless steel headers or downpipes, which will allow for greater flow rates resulting in more pops and crackles coming from your tailpipe when accelerating hard or letting off the throttle quickly.
Re-map your ECU (engine control unit) so that it increases fuelling at certain points during acceleration which can also lead to bigger pops and louder crackles from your tailpipe upon deceleration/downshifting gears
