About Flex Pipe

The flex pipe is a bendable tube that links parts of the exhaust system. The flexible exhaust pipe is used where it is necessary for the exhaust system.

Flex pipe concept

The flex pipe or flex tube is composed of stainless steel so that it gives the exhaust line enough flexibility when the vehicle moves. The component's flexibility helps reduce the cracks that could appear in the exhaust system if the pipe was stiff. Another benefit of the flex pipe is that it can take in vibration that is generated by the engine. The type of flex pipe material depends on the vehicle, a petrol car can fit a double braided, but a diesel can have three braided flex pipes.

Common complications with a faulty flex pipe

A faulty flex pipe can lead to uncommon sounds from the exhaust, poor fuel economy, and the smell of gas.
