What is a common method of repairing a leaky exhaust system?

The common method of repairing a leaky exhaust system is through the use of welds or clamps. This approach is effective because it can provide a durable and secure fix that restores the integrity of the exhaust system. Welding is often employed to repair cracks or holes in metal components, creating a strong bond that can withstand the high temperatures and pressures found in exhaust systems. Clamps are utilized to secure joints or connections, ensuring that they are tight and leak-free.

Other methods, while sometimes used, do not provide the same level of permanence or effectiveness. Sealing tape may offer a temporary fix, but it is not designed for high-temperature environments and may degrade over time. Replacing the entire system can be impractical and unnecessary when a targeted repair can solve the issue. Using putty might temporarily seal small leaks but generally lacks the durability required for long-term use in an exhaust system, where structural integrity is crucial. Therefore, welds or clamps prove to be the most reliable and efficient solutions for exhaust repairs.
