Installation Notes and Tips

Verify the vehicle year, make, model, and front-position application before installation. Confirm the 4-bolt welded inlet and 5-bolt welded outlet configuration, along with the two O2 sensor ports, against the original exhaust assembly. Because this is an integrated manifold and converter design, proper alignment of the exhaust flanges and sensors is important for a correct seal and accurate emissions-system operation.
