New BOSS in town

[PITT BOSS]

Can you explain those side exhaust restrictor plates? I haven't read anything about them.

The 2012 / 13 Boss' come with a "quad" exhaust. See attached photo of a failed parallel parking attempt with a pre-production prototype :p

The exhaust that exits the rear is typical with standard Ford mufflers (they sound ok). The side exhaust exits just in front of the rear wheels.

From the factory (presumably to meet noise requirements), Ford installed the above restrictor plates in the area that I highlighted in yellow in the below photo. The factory plates have a 1/4" hole and you really can't hear much from the side exhausts with these installed.

Three bolts each side and about 15 minutes total, the plates can be removed for "open" side pipes.

BIG difference!!!!!!!!
