What are the consequences of removing the catalytic converter?

[VanAlice]

The consequences of removing the catalytic converter are as follows: 1. The exhaust purification function is reduced, leading to excessive exhaust emissions, increased exhaust back pressure, higher fuel consumption, and decreased power: High-temperature sintering blockages will cause emissions to fail to meet standards, polluting the environment. Vehicles equipped with oxygen sensors will report faults. Unless the catalytic converter is blocked, removing it may improve power, but if the original converter is intact, there will be no significant power improvement. 2. The catalytic converter transforms harmful gases into harmless substances, so removing it is equivalent to emitting polluted gases. The catalytic converter is installed in the exhaust pipe and resembles a muffler in shape. Its outer shell is made of double-layer stainless steel plates, with an insulating material—asbestos fiber felt—sandwiched in between. Inside the steel shell is a high-temperature-resistant ceramic substrate with densely packed honeycomb-shaped small holes longitudinally.
