With long tubes you should get a custom tune. Your car will run fine without one (it'll run rich) but you are leaving a good 15-25 rwhp on the table by not tuning. Also, you will eventually get a CEL...you can drive with it or get a cheap obd2 scanner and delete them as they pop up assuming its related to the headers (02 sensor/cat codes).
