As a result, exhaust temperatures can increase and this can damage surrounding components (e.g. engine wiring harness, catalytic converter). This can create an unexpected loss of propulsion, increasing the risk of accidents and injuries. Moreover, this can increase the risk of fire. In addition, local statutory exhaust emission limits could be exceeded.
