    Not sure if they make a system for your application, but we have a complete Banks exhaust/intake on our 94 Chevy dually. Stock, they are a pig and the Banks system really woke it up with a significant increase in gas mileage. One of the few aftermarket systems that did everything they promised. Been on the truck several years with no issues. Was expensive but worth it. My only regret is I didn't do it when I bought the truck new. Would have paid for itself many times over by now.

    Raylar has a kit for pickups. Heads, intake, cam.

    I have a 2004 GMC 2500HD with the 8.1L It has the Gibson headers on it. I have a pair of spintec 3" mufflers also. It is a true dual exhaust. I have no tail pipes. It is loud, and sounds awesome!! Plus my mileage went up!! Very important with these 8.1 gas hoggs. It used to have a full Gibson set up on it out the back. The muffler was the round garbage can type. I hated it. Was 3" dual in and 2 1/2 dual out. WTF were they thinking??
    Like I said, HUGE improvement with true 3" dual exhaust!!
