Yeah taking all the cats off will eliminate all back pressure that your trucks needs to make torque.
You could always leave all the cats on, then put a y pipe where the muffler would be then put piping out the back or however you like it. I had that set up for about a week. Then I went back to the muffler shop and had a SI/DO magnaflow muffler put on. It's my favorite sound so far out of the 6 different exhaust set upsets I've had lol.
