How to Repair a Hole in an Exhaust Pipe

A vehicle exhaust system carries toxic fumes generated by the engine away from the passenger compartment. When an exhaust system leaks, exhaust fumes can flood into the passenger compartment, along high levels of carbon monoxide. Carbon monoxide cause headaches and can even cause passengers in the vehicle to become unconscious and eventually die.

Instructions

1

Raise the vehicle with a floor jack positioned at a secure point recommended by the vehicle owners manual. Stabilize the vehicle by placing a jack stand under each side of the vehicle frame. Lower the floor jack.

Remove loose dirt and debris from the area around the exhaust hole with a clean rag.
