"Emissions deletes" is a term used to refer to the act of removing certain components from a vehicle's emissions control system. These components include parts such as the catalytic converter (commonly referred to as the "cat"), exhaust gas recirculation (EGR) system, secondary air injection (SAI) system, and evaporative emission (EVAP) control system.
These components are essential for reducing harmful emissions, but they can also restrict the flow of exhaust gases and reduce the performance of the vehicle. By removing them, the engine can operate more efficiently, resulting in increased horsepower and torque. This is not always the case, though. For example, the Secondary air injection (SAI) system and the evaporative emission (EVAP) control system do not limit or hinder power output. Emissions deletes are not essential for increasing power output and are not recommended for street-driven vehicles. Significant power gains can be obtained without removing components from the emissions control system through a simple "reflash" or aftermarket software calibration.
While software reflashes are legal, emissions deletes are often illegal in many regions and can result in fines or other penalties if used on public roads. Additionally, the increased emissions from a vehicle with deleted emissions components can contribute to air pollution and harm the environment, making it important to consider the impact of emissions deletes on the environment. We do not recommend emissions deletes. Please understand that by unnecessarily deleting emissions equipment in your street car, you are putting a target on other car enthusiasts and tuner companies. By purchasing an emissions delete, you accept responsibility for the proper use of our products and commit to using them in compliance with your local laws.
