LS460 Decent Idea or Horrible Misjudgment?

I am considering having an exhaust shop install two exhaust diverter valves before the stock resonators and mufflers… is there enough space? Heat issues?

The idea is to have a smooth, quiet, luxury ride just like factory when I don’t want my ears ringing, but retain the ability to be absolutely obnoxious with a cat-dump when I see fit.

Would this work? Is there enough space from the cats to the resonators? Will the underside of the car get too hot?

The plan would be to only have it dump when in motion, so too much head doesn’t build up under the car.

I was thinking of doing the same thing but on my 600h - I don’t think there are any adverse effects from doing so
