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 headers are a shorty style header design, manufactured out of 14 gage mild steel or 16 gage stainless steel. The oxygen sensor is retained in the stock location at a collector. The headers may include a connecting Y-pipe that is also manufactured out of 14 gage mild steel or 16 gage stainless steel.
