* Illegal: Removing a catalytic converter is illegal in almost all jurisdictions. It's a violation of emissions standards and you'll face fines if caught. Inspections often include checks for the presence and functionality of the catalytic converter.
* Harmful Emissions: Without a catalytic converter, your truck will release significantly more harmful pollutants into the atmosphere, contributing to air pollution.
* Engine Damage (Potential): While the truck might run, the lack of a catalytic converter can, in some cases, lead to engine damage over time due to unburned fuel and increased backpressure. This isn't guaranteed, but it's a risk.
* Loud Exhaust: The exhaust will be significantly louder and probably more obnoxious.
In short, while it's physically possible to drive the truck, it's irresponsible, illegal, and potentially damaging to do so. Replacing or repairing the catalytic converter is the responsible and legal course of action.
