The inlet and outlet both utilize a 3 bolt welded flange design, providing a secure and leak-resistant connection to the vehicle’s exhaust system. The inclusion of an inlet gasket and hardware simplifies the installation process, while the single O2 sensor port allows for proper sensor placement to maintain engine performance and emissions compliance.
