Value of NOS Hi-po cast headers

[twisted2v]

Hey guys, I'm not familiar with the parts value of 60s Mustangs.  I have a pair of 64-66 NOS cast factory hi-po headers, and the H pipe.  Just wondering what these are worth.  C30E-9431-B and C4ZE-9430-A. Thanks!

Hi Twisted,

It is a small data set, but a nice used or NOS or restored pair sold recently on a popular auction site for just under $800.  See eBay No. 295108456501.

I nice used set sold for an offer under $500.  Can't tell the actual selling price.  See eBay No. 326236578433.

There is a NOS with a BIN price of $4000.  The seller is dreaming.  The manifolds have been on auction for a long long time.  See eBay NO. 354640277050.

Its not clear if your H-pipe was NOS or repop.

Best of luck

Cory
