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 JBA Header kit includes two header manifolds, gaskets, and necessary hardware. The JBA Headers are a shorty style header design, manufactured out of 409 16-gauge stainless steel and are intended to replace the factory exhaust manifolds. The factory 02 sensors, if applicable, are retained in the stock location at a collector.
