Finally installed the Doug Thorley Catback system after installing the headers. I can say, I am very impressed with how well everything is made. I've bought several other exhaust components over the years for various vehicles, and even a full race exhaust for my last Tundra; the Doug Thorley kit blows it out of the water, its well made from the front all the way to the back.
My only gripe, the driver side pipe that comes off the cat and over the transfer case is too close the the underside of the body. I had to crawl under my truck again and loosen all the hardware and get on it with a pry bar after it was all installed to get it to stop vibrating on. I also installed reflective aluminized tape to avoid any unnecessary heat transfer through the floor.
Other than that, it sounds amazing and it really makes that V8 come alive. It definitely catches bystanders by surprise when accelerating from a stoplight or on the highway.
