I currently have spoon 4-1 header on the car now and a spare DC header, Which one is the better header.

 

If it's a real spoon than that is better. But there is a lot of ebay garbage sold as spoon.

 

How can you tell if it's fake? It has the logo welded on the cylinder 2 runner.

 

I doubt its real. Spoon hardly ever dealt with F22s and H22s. They almost stuck exclusively to B series in the the 90s.

In addition, a real Spoon header will have a JASMA serial number, to prove its passed inspection by the Japan Automotive Sports Muffler Association.
