What CAT to buy? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Im going to start buyig the components of my exhuast. First thing I will buy will probly be the headers. I will most likely have them Jet Hot coated. Then muffler and cat. Then I will go down to a local muffler shop and have them install everything from the Y pipe back. Unless I can find a kit, then I will do it myself.

How big is the output on the Y pipe that comes with these headers? Is it 3"?

If so I want to run a 3" pipe from the Y to the cat then to muffler. Muffler to split the 3" to two 2-1/2"'s and have them exit behind rear tire on each side.

Anyone make a kit like that?

What CAT should I buy? I want a good high flow CAT, that will still work well for emissions.
