hey guys. just bought these rewarder tt headers that are ceramic coated with water lines. i guess these are rare for a 455 ? got a steal on them. are these pretty simple to install ? my boat had logs and snails on it before and i switched to bassets. i have the headers but not the tubes or tips so if anybody has any they want gone ill will buy them. I know kaotyk had them on his tahiti so im gonna look through his thread but still will need some help
