What Is Exhaust Backpressure And How Does It Affect The Engine? Backpressure from the exhaust can lead to several problems. If the engine can’t breathe because the catalytic converter is blocked up, the engine won’t work as well and will use a lot more gas. And even if the converter completely stops working, it can still stop the engine. The very exact thing could occur if the inside of a silencer, a resonator, or a double-walled exhaust pipe breaks. Anything that slows down the flow of exhaust will cause the exhaust system to have too much back pressure.
