No tune necessary except to turn off the rear O2 sensors.
OP: Go to any of the many sponsor websites and look on there. There are plenty of choices and they pretty much all work fine. I prefer the Prochamber over the H myself. Go to YouTube and listen to clips, see what you like, though the sound is more in the different mufflers rather than the different midpipes, aside from the difference between catted vs O/R and H vs X vs Prochamber, different brands mostly sound similar.
