* Emissions: The catalytic converter is a crucial part of your vehicle's emission control system. Removing it will result in significantly higher levels of harmful pollutants being released into the atmosphere, leading to air pollution. This is illegal in most jurisdictions and can result in hefty fines.
* Engine Damage: The catalytic converter helps regulate exhaust backpressure. Removing it can alter the engine's performance negatively, potentially leading to damage in the long run. This could include premature wear on engine components.
* Performance: While some believe removing it increases performance, this is usually negligible and often outweighed by the negative consequences. You might see a slight increase in horsepower and a change in exhaust sound, but you'll likely lose low-end torque.
* Inspection: You will almost certainly fail any emissions inspection required for vehicle registration.
* Legal Ramifications: As mentioned, removing the catalytic converter is illegal in most areas. Law enforcement may fine you or even impound your vehicle.
In short, while it might seem like a simple modification, removing the catalytic converter from your Jeep TJ is highly discouraged. The risks far outweigh any potential benefits.
