Yes those will work, if you look at the muffler that Dynomax recomends it is the A style of the Flowmaster.
I am going to get basicly the same set up for my K5 and Burb, but I am getting Hedman headers.

If you want some serious sounds from your truck you can buy a set of warlock mufflers. They have a bypass plug that is held on with 3 wing nuts. Noise isnt bad and when you want to hit the strip or sound good for a drive in just pop out the plugs. These things GRAB attention when the plugs are out!!
