What are the consequences of a leak in the middle section of the exhaust?

Here are the consequences of a leak in the middle section of the exhaust: 1. If the leak is in front of the muffler, it will cause increased noise; 2. If it is in front of the catalytic converter, it may affect the quality of the exhaust emissions, potentially causing the vehicle to fail an inspection. Here is some related knowledge about the exhaust pipe: 1. Function: Installed between the engine exhaust manifold and the muffler, it provides flexible connection for the entire exhaust system, thereby reducing vibration and noise, facilitating installation, and extending the life of the exhaust muffler system. 2. Application: Exhaust pipes are mainly used for light vehicles, micro vehicles, buses, and motorcycles. The structure of the exhaust pipe consists of a double-layer corrugated pipe covered with a steel wire mesh sleeve, with clamping rings on both straight end sections. To improve the muffling effect, expansion joints or mesh sleeves can be installed inside the corrugated pipe.
I've got plenty of experience with exhaust mid-section leaks. A leak causes the exhaust system to lose necessary backpressure, directly reducing engine power. You'll feel sluggish acceleration when driving, and fuel consumption increases. What's worse is the significant noise increase – it sounds like a broken drum buzzing, especially annoying on highways. Leaving it unrepaired long-term can affect the oxygen sensor, causing false trouble codes and making repairs more complicated. I recommend regular exhaust pipe inspections, especially for older cars with high rust risks. Don't ignore minor issues that could lead to major problems. When parking, be aware that exhaust fumes may escape through leaks, affecting health. In short, timely troubleshooting is key – don't wait until performance deteriorates to regret it.
