Contact your local dealer and have them run the vin number. They can tell you if you have the air injection valve. I think that only comes on vehicles made to California emissions laws. Also, I would seriously think about buying the Gibsons. We did a side by side comparison of the stock manifolds and the gibsons, and they hardly flow better than the stock manifolds. Plus, for the money, Summit Racing sells a set of long tube Doug Thorley headers for $428. With these trucks, it's always better to go with at least mid lenght headers, and even better long tubes. Shorties really aren't worth the money when compared to the price of the Thorleys.
