I ran a sailcloth replacement top for a few years on the factory hardware on my 93 YJ. For the money I paid for it, I did not see the big difference in quietness or insulation. It was noticeably thicker, but was not any quieter at highway speeds. It was however noticeably harder to get installed. It kept getting worse and worse each year. Its like it was shrinking. It got to the point unless it was setting in direct sunlight on a 80+ degree day, you were pretty much not going to get it in the rails and get the snaps over the doors snapped. It was also hard to fold it up when taking it down cause the cloth was so stiff. I eventually got fed up and bought the standard replacement top. It fits so much better, its not any louder, it has not shrunk in the 3-4 years I have had it now, and its still easy to put up and down.
My opinion, save your money and buy the standard replacement top. Do not waste your money on the sailcloth.
