What is the proper method for inspecting internal baffles and diffusers of an exhaust system?

The proper method for inspecting internal baffles and diffusers of an exhaust system is through disassembly and visual inspection. This approach allows for a thorough examination of the components, ensuring that any potential issues such as cracks, corrosion, or blockage can be identified clearly.

Disassembly is particularly important because internal components like baffles and diffusers are not always accessible from the exterior, and a visual inspection while the system is disassembled provides a complete view of their condition. Inspecting these components while they are in place may not reveal hidden problems that could affect the exhaust system's performance and safety. This method ensures that all potential issues are addressed, which is essential for maintaining the integrity and efficiency of the exhaust system.

Other methods like pressure testing or ultrasonic testing can evaluate certain aspects of an exhaust system but may not be suitable for inspecting specific internal features like baffles and diffusers comprehensively. Visual inspection alone without disassembly could miss critical issues that are only observable when these components are fully accessible.
