I have this exhaust on my car currently, but still have the cat on the car. Test pipe is sitting on the floor awaiting install. I was wondering if anyone has gone from a cat to no cat with this exhaust. It sounds pretty nice as it is. My hope is that the dreaded drone does not appear once the test pipe goes on. I live in FL so no emissions required. If anyone has this system without the converter, I'd love to hear your thoughts.
