We show basic details only for this EO. Its vehicle list is not a ruled table we can read reliably (often a scanned table or a list in the text), so we do not copy it. Check the vehicles and part numbers in the original PDF.
What the EO says about the part
The AFE Exhaust Manifolds are a pair of direct fit cast iron exhaust manifolds that bolt to the stock connecting pipes without any modifications. They retain all stock connections and require no modifications for installation. This Executive Order is valid provided that the installation instructions for the AFE Exhaust Manifolds will not recommend tuning the vehicle to specifications different from those of the vehicle manufacturer.
