Elio Addict
GM been using plastic intakes for at least 10 years, probably will be plastic on Elio also. Exhaust my actually be "borrowed" from ???? eo maybe, If tooling still exists ???
A cast in exhaust on he head would have to be visiable already in the casting development, would be an "interesting " part to cast. Cheaper to bolt it on ,I think.
