This aftermarket automotive component replaces the catalytic converter in a vehicle’s exhaust system. Typically constructed from metal tubing, its primary function is to provide a less restrictive path for exhaust gases to exit the engine. By removing the catalytic converter, which is designed to filter pollutants, this device allows for increased exhaust flow.
The principal advantage cited by proponents is the potential for improved engine performance, particularly in terms of horsepower and torque. The reduced backpressure in the exhaust system can lead to more efficient engine operation. Historically, these components were often employed in racing applications where maximizing performance was paramount, even at the expense of emissions compliance. However, it’s critical to acknowledge that removing or altering a catalytic converter may violate emissions regulations in many jurisdictions.
