The exhaust is catback, just undo the clamp over the rear axel and pull off the original exhaust and slide on the Gibson dual.
I have a 2012 unlimited and it fit great and sound cool with no drone on the 3.6.
Black with Deep Tinted windows. bestop-product fits 2007-12 unlimited.
The top can be completely unassembled with labels and instructions to put back together for easier shipping but pefer to sell local or meet due to bulk.
