66 Dart GT HT Whatsitgonnabe?

And I suppose my '66 273 manifolds wouldn't have them, right?

When we're talking manifolds, this exhaust throttle, does it serve any purpose? Mine is seized in the fully open position, so I guess it's pretty useless anyhow, but I'm thinking I should rip it out. I saw someone who did that here on FABO.

Good idea?
