It will need tuned. So don't change the parts out until you can tune it. Ideally, you would have the tune and exhaust swap done at the same time.

One other thing to understand if you change this part of the car out: the removal of the catalytic converters means you are removing the air-cleaning elements from the exhaust system. It will smell like you have a pre-cat exhaust leak all the time and your MPG will decrease if your car is tuned to run a little rich (to take advantage of the removal of those restrictions). This is considered an off-road modification and isn't recommended for a daily driver.
