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.

Now u say u have no cats now ? How did u remove the top end ones? By removing an adding or cutting them right there on the spot. An that didn't throw any codes

I have the sensor codes. I bought a down pipe fix but it isn't configured right just yet.
