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 Dinan Header System is a pair of long tube headers manufactured out of 16 gage stainless steel. The headers are designed in the configuration of 4:2:1. The oxygen sensor remains in the stock location at the collector of the exhaust system.

Quoted from EO D-176-24. The EO exempts the part from California Vehicle Code Section 27156 only for the vehicles it lists.
