Re: Ram horn headers hidden lever?
Hello, I don't get a chance to help that often so I thought I would put my 2cents in. As jim said its a heat riser, there is a coil on it that heats up from the heat of the exhaust and opens a butterfly inside the pipe flow. The counter weight keeps it in the restricted position the Tie wire might mean its broken and not working. I think its to help the crossover heat in the intake when its cold. Lots of them are removed when not needed. hope this helps.
