Which risk increases when a catalytic converter is fouled?

💡 Explanation

Engine backpressure greatly exceeds limits because the accumulation of deposits in catalytic converter restricts flow via increased surface area resistance. This leads to increased upstream pressure rather than reduced reaction rates; therefore backpressure increases, rather than other kinetics shifts.
