Welcome to the forum!

As Corey stated above chips are not available for your year of truck. Just programmers such as the gryphon.

Rule of thumb for exhaust on these trucks.
Any thing from the cat back to the "y" is ok.
3" max si/so 3"
3" si/do 2.25 or 2.5
Above options preferable with muffler.
You can mess around with anything on the exhaust except for long tube headers they need a tune or going over the sizes listed above.
Don't remove the cats either if you want replace them with high flow ones.
