What is the flex pipe in a Toyota Highlander?

The flex pipe in a Toyota Highlander is a flexible section of the exhaust system that accommodates engine movement and vibrations while helping to reduce noise and exhaust emissions. It is typically located between the exhaust manifold and the catalytic converter, allowing for slight movements of the engine without causing stress on the exhaust components. This design helps prevent cracks and leaks in the exhaust system, contributing to overall performance and longevity.
