E-cutout on my LS430
And it isn't much of a cat as it is a resonator. At least that's what my muffler shop was saying.
Anyways, so after removing the 3rd cat, your engine light WILL NOT come on or light up.
The O2 sensors are located right before it so it doesn't matter, and it doesn't throw a code unless you remove the first catalytics.
Car sounds 300% more angrier now after the 3rd cat delete. I'll be sure to upload some vids.

So I just had my 3rd cat removed this weekend. The videos here of the car have the 3rd cat still.

Plus I've also heard it acts as a muffler/resonator as well. You said it sounds a lot angrier so do you think the drone is a lot worse after removing the third cat?
Oh yeah, the drone is so so bad at times, the car's interior vibrates. I have straight pipes instead of the 3rd cat, so that's why it drones really bad. But what I do is not open the cutouts fully, I open 1/4 of the way, and it sounds awesome with zero drone.
If you don't want the drone, get a glass pipe instead of the 3rd pipe. It'll sound great.

One of these years, somebody will post a vid of a car with stock pipes, then stock pipes with C/Outs open, then stock with resonator delete, then resonator with ...etc.
Trying to decide which choice to go with is tough with all the variables not progressively laid out.
Drone is the biggest killer. We have a Z06 and if you "pull the fuse" to open the exhaust, the drone at 70 is horrendous.

Here is a clip I took tonight.

Check out my build thread for photos. My setup is basically as follows;
Both 2nd catalytics removed, custom x-pipe instead.
Deleted resonators. Straight pipes.
Dual remote cutouts right before the muffler.

I think the pipe size was 2.5, because factory was 2.25, so I vividly remember the mechanic saying the lip on the 2.5 piping would hold up pretty good and tight with stock.
The first video is just the resonator delete + cutout. The E-cutout is bypassing the mufflers, which do an outstanding job of silencing the car, one of the best mufflers I've seen around.
My car is almost stock when the cutouts are closed and not bypassing the muffler. Even with the primary resonators deleted(straight pipe) and the secondary's replaced with an x-pipe, car is almost stock when the cutouts are closed.
So if you want your car to sound anything louder, that muffler has to be bypassed, or removed, which I don't recommend.
Good luck.
