Exhaust Flex Pipe Repair and Replacement

Exhaust Flex Pipe

Can I replace my broken flex pipe? This question is asked often. However, before I explain how to repair a Flex pipe, it is crucial to understand what the Flex pipe does and its functionality.

 A Flex pipe, also known as Flexible, Flexi, Flexy Flex, Braid, interlock, etc. is a crucial component fitted to a vehicle's exhaust system.

Mainly fitted to vehicles which have a transverse engine, there needs to be a section of the exhaust which can move with the engine. If the exhaust is too rigid, then the system will crack and break, especially near the expensive manifold. Therefore, to reduce the chance of this happening a flexible tube is fitted; generally, after the downpipe, this will significantly reduce noise and vibration and prevent damage. Exhaust pipes get extremely hot from the gases passing through the system and out the tailpipe. Due to this, when an exhaust system needs to bend, shift, expand, or be flexible, the manufacturer cannot use traditional materials like rubber. The flex pipe made of metal, strips are woven into a lattice or braid and thus can withstand exhaust gas heat. Cheaper Flexi pipes are made from mild steel but do not last long; stainless steel is the preferred choice which is built to last longer.

The flex pipe is a great solution but also creates another problem, and that is, it does not last forever. Eventually, constant movement causes the flex pipe to fracture and break. Furthermore, it is not just wear and tear that will cause the damage, it’s also knocks, bumps and grazes, if the vehicle was to hit, maybe a speed bump and any other anomaly on the driving surface, this can also cause the damage.

Manufacturers install the Flexi pipe as a non-removable part, which welded in place. Excellent for the manufacturers because they can sell you a complete downpipe which can cost hundreds and even thousands of pounds, not so good for the vehicle owner because this certainly means a huge bill.
