On the facelift version, there are two secondary cats in the center tunnel section, then the suitcase muffler in the back.

The mod is to cut out the secondaries and replace it with the magnaflow in the same place in the center tunnel.

Its a tight fit but the part number I listed works on mine and only has about .5" exposed from the bottom. Its louder and deeper but not to where it's annoying. Video is above. Power increase is negligible.
