The ceramic catalyst inside a catalytic converter is made from a lightweight, thin-walled, fragile material. It is protected by a dense, insulating mat. This mat holds the catalyst in place and provides moderate protection against damage. However, rock or road debris s triking the converter or improper or broken exhaust system support can cause a Catalyst Fracture . Once the ceramic catalyst is fractured, the broken pieces become loose and rattle around and break up into smaller pieces.
Flow is interrupted and backpressure in the exhaust system increases.
This leads to heat build up and loss of power. Possible causes of a catalyst fracture are road debris striking the converter, loose or broken hangers, potholes or off-road driving.
