I realize it's difficult to see without taking them off the car, but does anyone reconize this header?

Thanks much,

I am not an expert,,,,,,,,,,,,,,,to me they look like vintage INTERPART headers.

That'd be neat. I'll check the catalog tonight. Thanks

They are identical to what I had on 721. I think they are Interpart.

Chris was nice enough to send me a copy of this catalog earlier in the year; never thought to look here. Figured they'd be generic. Sure enough, looks like that's the header. Wish there were product reviews available from the early '70s; I imagine a good amount of engineering has happened in the past 40 years, but does anyone know if these things breath well enough?

they did for BRE back in the day...................

Good enough for BRE = Good enough for ME.

I thought BRE built their own exhaust system.

Well, it depends on which BRE you're referring to: The BRE race team or BRE parts. The race team did build their own headers and some their design was then used by Internpart to make and sell the headers you see in the BRE Parts catalog.

this old add, if you enlarge it indicates that the headers are built by Cyclone ..... FWIW............so civilians got these and hardcore racers got the BRE/Interpart in 1972 ?

I believe that's the point I'm making. Thx.
