bigbaddiesel:<br><br>Yes, my exhaust manifold "is different from stock." 
<br>It is made by "Advanced Turbo Systems" (ATS) and<br>is a three-piece unit. It is supposed to made with a<br>better grade of iron that is not so prone to "shrinking"<br>and distortion under real high heat conditions as the<br>stock manifolds do. The twelve valve manifolds are<br>bad about cracking around the #1 cylinder near the<br>tab or "boss" that protrudes out from the head.<br>The 24 valve exhaust manifolds crack in or near<br>the middle. The "three-piece" construction of the<br>ATS manifold allows the manifold to "expand and<br>contract" as it gets hot and then cold again. ATS's<br>literature states that it flows about 10% better <br>than the stock unit. I saw no increase in H.P.,<br>but my EGTS were definitely lowered some and<br>the throttle response felt better.<br><br>Most of the major vendors have the ATS manifold.<br>I bought mine from Scheid Diesel. After buying it<br>I had it ceramic coated by "Jet-Hot."<br><br>Hope this has helped you.<br><br>-------<br>John_P
