2012 Jeep Wrangler Unlimited - Great product. Sounds good but not too loud. Very easy installation! Make sure you soak all your old clamps in WD40 for a few days before removing them. This kit is FULLY bolted on with no cutting required. All details fit perfectly. The hardest part of the installation was removing the old rubber bushings. Using a long flathead screwdriver or a combination of a 1" and 2" pry bar helped a lot. After assembly, the exhaust does not flow! Installation time was approx. 1 1/2 hours including dismantling of the old exhaust.
