Hey MiB,
Welcome...
If your new Exhaust is minus a Cat. then there is a good chance you will need to re-tune the Air Fuel Ratio with a Fuel Controller of some sort and a dyno run. The Auto Tune gizmos, that a few companies sell, work well but require a larger O2 sensor to be installed.
If your new Exhaust still has a Cat. and you've re-fitted the O2 sensor from the OEM Exhaust, then you don't need to do anything...
