“Pops and bangs” are created by unburned fuel in the exhaust system. When excess fuel enters the exhaust system it increases in temperature and ignites inside the exhaust instead of the combustion chamber. The noise can be exaggerated by fitting a decat or full decat exhaust system.

What does it mean if your exhaust is popping?
Poor Fuel-Air Ratio When combustion doesn't happen in a timely manner, the exhaust valve opens while the air-fuel mixture is still igniting, causing this explosion to “spill” out of the cylinder, making a loud popping noise. In newer vehicles, computerized sensors help ensure the air-fuel ratio is correct.
What causes exhaust popping on deceleration?
Decel popping is caused by the detonation of unburned fuel in the exhaust pipe. This happens with high flow exhausts that allow more fresh air to be pulled into the pipe, causing the exhaust temperature to rise and detonate any unburnt fuel.

Why does my exhaust make a popping noise when I accelerate?
Loose exhaust pipe or muffler If you hear popping when accelerating, it's likely due to an issue with your fuel mixture or ignition timing. If you hear the popping sound at all times, it could be coming from your suspension or tires.
Why does exhaust pop when I let off the gas?
An afterburn or backfire from a vehicle's engine on deceleration happens when unburnt fuel combusts or ignites in the exhaust pipe. The result is a loud bang or pop when you move your foot off of the gas pedal. Take note that this instance can occur in many vehicles, including trucks and motorcycles.

Are Car Exhaust Crackles & Pops Fake?
How do I stop my exhaust from popping?
Block off the fresh air injection systems. This will reduce the air being fed into the exhaust, causing the higher exhaust temperatures and detonation. 2. Adjustment to the fuel table in the zero percent fuel column from 2,000 rpm to redline, may also be needed to help reduce popping.
Why do exhausts pop and crackle?
If you have an exhaust sound that is crackling and popping, it's likely due to steam or water in your fuel system. When the engine is cold, condensed moisture can collect in and around the exhaust manifold if there are any leaks of coolant from hoses or seals.

What does a popping exhaust mean?
When an engine is running rich, it has too much fuel and too little air, which slows down the combustion process. When combustion doesn't happen in a timely manner, the exhaust valve opens while the air-fuel mixture is still igniting, causing this explosion to “spill” out of the cylinder, making a loud popping noise.
Why does my truck pop when I press the gas?
When you hear popping or crackling sounds from a vehicle, it is usually due to unused fuel exiting the engine. It gets ignited by the hot exhaust system to create unwanted sounds. It often happens after hard acceleration, right when the throttle gets left off, because an overrun occurs.
