Why does my motorcycle’s exhaust pop?
For motorcycles with too high flowing exhaust, their large openings and short pipes allow an excessive amount of air back in the exhaust system. This makes it difficult since any amount of unburnt fuel will detonate and cause the popping. For other cases, the carburetor can be adjusted to reduce the popping significantly.
Why does my car make a pop-pop sound when I accelerate?
And the unburnt fuel that comes out of the engine to the exhaust, mixes with the higher temperature air in the exhaust system. And when this unburnt fuel meets the high temperature air, the detonation happens – resulting in a pop-pop sound. More commonly referred as popping.
What is deceleration popping in motorcycles?
Decel popping, i.e. exhaust popping during deceleration, is in fact a common phenomenon in motorcycles with high flowing exhaust system. Shorter the length of the exhaust pipe and larger its opening, higher is the air flowing in the exhaust.
How do I know if my motorcycle has a high flowing exhaust?
If your motorcycle has a larger opening at the back and a short pipe, then it has high flowing exhaust system. Decel popping, i.e. exhaust popping during deceleration, is in fact a common phenomenon in motorcycles with high flowing exhaust system.

Some of these pop and bang tunes also have the spark plugs fire as the fuel is leaving the cylinder through the exhaust ports by massively retarding (delaying) the ignition timing. This can result in the burning of your exhaust valves, which can either cause them to no longer seal properly or damage them permanently.

What causes backfire through the exhaust?
The spark inside the chamber may not burn up all the fuel, allowing a little extra gasoline vapor to enter the exhaust, and lead to a backfire. This can be caused by a faulty mass airflow sensor or a clogged engine air filter "choking" the engine and not allowing enough oxygen to flow into it.

Why does my exhaust pop on deceleration?
Exhaust Popping on Deceleration. Deceleration backfire is caused by fuel burning in the exhaust manifold or header. Something you should understand before going any further is that a motor in perfect tune will exhibit deceleration backfiring.

First, when you close the throttle, you are also closing the throttle plates. This reduces the air and fuel floating into the motor, and increases the vacuum. This results in less air and fuel in the cylinder during the power stroke, which results in a lower pressure in the combustion chamber.
Why does peak pressure change off throttle?
This changing of where peak pressure occurs off-throttle, apparently, is “specifically done to prevent turbo lag” in the Veloster N’s N Mode.
What happens when you let off the gas pedal on a Hyundai Veloster?
In the Hyundai Veloster N, according to Feske’s conversation with Hyundai’s reps, when you let off the gas pedal the engine actually waits until the exhaust valves are open to ignite the air and fuel mixture, allowing a lot more noise to escape.

Hyundai didn’t invent this concept, but it makes a pretty good example of how those intense “gunfire noises” you hear coming from the car aren’t exclusively for theatrics.
