Just bought a pair of 572s and the guy also had a very nice set of gaffrig headers. I am going to pressure test them next week but cannot find any info on them.

I know Gaffrig made mufflers, but never heard of them making headers.

never seen headers from them nor were they ever in their catalogs years past

Here is a video of them.

Those were made by the original Jim Gaffrig back in the day. I can't tell you exactly when as my memory is toast but at the time there were not a lot of choices when it came to stainless headers. I think he only made a few prototypes and never got into production.

The video does not do them justice. They look to be very well made and are heavy as crap. Just couldn't find any info. Being prototyes would make sense. These came from an older gentlemans personal stash who has a nice collection of older boats he restored. He was going to use these and the motors I bought for a 38 cigarette project but decided against it and sold the boat.

Never seen any headers like that. Not sure whats up with the youtube link. It worked for me and all I did was copy and paste
