This weekend I took the truck down to my local muffler shop and had the two cats removed and had one high flow cat installed. The second cat was 50% stopped up. Also installed a K&N air filter. When I filled up the truck added some octane boost and went after the trailer for a test run with the new changes and boy what a change she can stay at 65MPH without having to down shift all the time it still pings some but working with the timing will help that I hope. Adding some shorty headers I some sure there will be a difference i appreciate everyones comments it sure made a difference.

The only problem to solve is the surging when the truck is started the canister in question always sucking air in not out any comments on my surging issue.
