Taco Warmers or Performance Headers?

I had no idea they were Power Pipe DC ...
I put Taco Warmers in the title thinking that some Bar B Que pit builder made them.
They make me hungry when I look at them,start thing of cook something.
Might use them on my 1972 Dart with a 2 into 1 pipe to push a small turbo for the friendly on the cheap competition.
I too have heated a lot of things on exhaust manifolds when camping and it does bring back some memories...
