What Happens If a Plastic Bag is Stuffed into a Car's Exhaust Pipe?

If the exhaust pipe is blocked, the car may experience weak acceleration or idle shaking. Therefore, when no other causes can be identified, it is advisable to check whether the exhaust pipe is blocked. Here is some relevant information: Specific reasons: When a car is running on the road, gasoline burns relatively completely, usually producing carbon dioxide. If the exhaust pipe is blocked, incomplete combustion of gasoline occurs, leading to the emission of carbon monoxide. Since carbon monoxide and exhaust gases cannot be blown away by the wind, they accumulate around the car and can easily enter the cabin. Additional information: Passenger cars are primarily designed and technically intended for transporting passengers and their personal luggage and/or temporary items. Including the driver's seat, passenger cars have a maximum of nine seats. Passenger cars are divided into the following 11 types. Mainly: standard passenger cars, convertible passenger cars, luxury passenger cars, compact passenger cars, roadsters, hatchback passenger cars, station wagons, multi-purpose passenger cars, forward-control passenger cars, off-road passenger cars, and special-purpose passenger cars.
I've heard quite a few similar incidents, and stuffing plastic bags into a car's exhaust pipe is truly terrifying. Think about it—once the exhaust pipe is blocked, the exhaust gases can't flow out smoothly, causing the engine to suffocate like holding one's breath, quickly stalling or failing to start. Even worse, if it suddenly stalls while driving, the car could lose control, leading to rear-end collisions or other accidents, posing significant personal safety risks. Long-term blockage might also damage the catalytic converter or muffler in the exhaust system, costing hundreds or even thousands to repair—not worth it. I always avoid parking near garbage piles, especially in rainy weather when plastic tends to accumulate. If this happens, you must stop and check immediately to prevent bigger trouble. In short, don't do this as a joke—it's far too dangerous.
Once my friend's car was pranked with plastic bags stuffed into the exhaust pipe, completely blocking it. The engine sound became extremely loud, and the car stalled immediately upon starting. He was frantic. With the exhaust pressure trapped, prolonged overheating occurred, dashboard lights flickered wildly, and there was even a risk of flames. He eventually called a tow truck, which took most of the day. The mechanic said small components were burned out, costing hundreds to fix. Since then, we've made it a habit to check around the exhaust pipe when parking, removing any plastic or leaves. Neglecting such small issues can leave your car completely immobilized—costly and troublesome. Prevention is key: keep the area around your car clean.
