No, the only exhaust upgrade that needs a tune is long tubes.

Only if you delete the rear O2 sensors would you need a tune; long tube headers need a tune adjustment due to the relocation of the front O2 sensors further away from the stock location (to adjust the delay).
Otherwise no tune change is needed.
