What causes the popping sound from the exhaust pipe of the 10th-generation Accord?

The reason for the popping sound from the exhaust pipe of the 10th-generation Accord: excessive moisture in the fuel. After the combustion of the air-fuel mixture, it produces a large amount of carbon dioxide and water vapor. When the temperature is too low, the water vapor condenses into water, which over time can cause the car's exhaust to produce a popping sound. The 10th-generation Accord is a mid-size car launched by GAC Honda, with dimensions of 4893mm in length, 1862mm in width, and 1449mm in height, and a wheelbase of 2830mm. The 10th-generation Accord is equipped with a 1.5T turbocharged engine and a 2.0L naturally aspirated engine, with maximum horsepower of 194ps and 146ps, and maximum torque of 260nm and 175nm, respectively.
I also experienced similar issues with my 10th-generation Accord. The chugging sound from the exhaust pipe is quite common, usually caused by exhaust system leaks or engine ignition failures. Loose exhaust pipe connections, rusted-through sections, or pipe cracks can lead to gas leakage, producing that chugging sound, especially noticeable during acceleration. Ignition-related problems like worn spark plugs, damaged ignition coils, or clogged fuel injectors can cause incomplete combustion in some cylinders, affecting power output. Additionally, with the 10th-generation Accord's small-displacement turbocharged engine, carbon buildup is more likely in stop-and-go city driving, exacerbating these symptoms. I recommend checking the dashboard for warning lights immediately upon hearing the sound. If there's abnormal noise from the engine compartment, be extra cautious - don't force the car to run to avoid damaging other components like the catalytic converter. For prevention, regular maintenance with spark plug replacement (typically every 30,000 km) is advisable. If you're not mechanically inclined, getting a professional inspection early can save major repair costs later. Safe driving should always come first.
My 10th-gen Accord's exhaust pipe was making a popping noise earlier, and after some troubleshooting, I found that the connection at the tail end of the exhaust pipe was loose. Tightening the bolts myself partially resolved the issue. However, experience tells me this sound is often a sign of ignition system problems, such as worn-out spark plugs or poor contact in the ignition coils, especially during cold starts when the popping is more pronounced. The Accord's 1.5T engine frequently experiences such misfires in city traffic jams. I recommend idling the engine in a quiet parking lot to pinpoint the source: if the sound comes from beneath the engine, it might be time to replace the spark plugs; if it's from the rear, check the exhaust pipe. Don’t delay too long—a friend of mine waited months and ended up spending over a thousand dollars on engine repairs, not to mention the impact on fuel efficiency and performance. Now, I’ve made it a habit to regularly inspect my car to prevent these minor issues, saving both time and effort.
The rumbling sound from the 10th-gen Accord's exhaust pipe is quite annoying. Let me share some simple self-check methods. First, park and turn off the engine, then open the hood and start the engine in idle state to carefully locate the sound source: if it's coming from the rear exhaust pipe area, it might be an air leak at the joint—check for rust or loose bolts; if the rumbling comes from the engine area, it's likely an ignition issue like spark plug problems. Also, check if the engine warning light on the dashboard is on. Turn off the AC to test—if the sound changes, it points to load-related issues. The Accord's turbo system tends to accumulate carbon deposits under frequent start-stop conditions, so I recommend timely spark plug replacement or fuel system cleaning to prevent such sounds. If it's too difficult to handle, just visit a repair shop—don't let the problem escalate. Safety first.
