Need advice fabing up an exhaust

Hi yall, ive been wanting to get 2-step installed on my car for a long time now but where I live is very strict on having catalytic converters, so unfortunately I have to keep them on, and since im keeping them on the 2-step will destroy them in seconds, so I was wondering if i can figure out some sort of system to where, I push the button for the 2-step it could also open up a bypass valve so my cats wont get destroyed, do yall think just a basic qtp cutout would work or should I go full blown and get a "true" bypass valve, where the side pipe opens meanwhile the main exhaust pipe closes so the exhaust gases doesnt hit my cats but it just vents straight to the open?

You didn't hear this from me....

Punch out the catalyst material so that your cats are hollow, and then you don't have to worry about them.

Worth a try. Good luck, and it will sound a bit louder with them hollowed out.
