Hey Giaka,

That all depends on whether or not you are re-using or deleting your factory catalytic converters.

If you are purchasing an after-cat X Pipe or something similar which re-uses the stock cats then you do not need to re-tune the car.

If you will be running an off-road Mid-Pipe then you would want to get the tune updated, which Bama will do for free as long as you are a free tunes for life member!

Hope this helps and let me know if you have any questions!
