i did it on the stock muffler with resonator. Sounds just like a big floppy fart. I have no cats at all anymore. I would love to hear your setup though after you take them out. All a shop needs is 1 vibrant U-J bend of 2.25" material to pull it off. The bends are almost a perfect fit if you cut at the right point.
