2. Installation Complexity: installing headers requires some level of mechanical expertise and experience. The process can be time-consuming and may require additional modifications to the exhaust system.

3. Heat Management: headers can generate a significant amount of heat, which can be a challenge to manage, especially for older vehicles without adequate cooling systems.
