Well after a long struggle with JBA to get all my parts in my hands(two attempts to recover unpackaged parts) I took my truck to the muffler shop, same one that has done all my vehicles, so i know they are not dumba$$ s', for the install. I was there for four hours! All the hangers were in the wrong spots, the cat back pipes needed to be cut down so they wouldn't hit my frame and my the underside of my bed. It is loud and does sound good, I can't imagine how loud it would be with the cats out. Take this post how you want, If you order something from JBA stree them to triple check your boxes before they ship them, while they did overnight my missing parts, it was still a pain in the butt.
