B16 or B18 header? Yes, b16 headers are shorter and b18 headers are taller because of the difference heights of the decks. I have one I am willing to sell to you for $100. The only problem is that I am still using it, meaning I will need to find a manifold and stock downpipe to replace it. It is a Hedman Chikara B18A header. The upper half is wrapped and was VHT paint coated and cured prior to the wrap. The wrap is also sealed with black header wrap sealant. The lower half was VHT painted and cured with VHT paint as well. Overall, it is in mint condition.
