the doohicky on the exhaust was a finch bird feeder and flame thrower . My boys ideal and i liked the look. I am making a new exhaust now, its a header i just made. I still have to get a new gasket and some copper tubing for a heat riser to the manifold and i think some header rap to be complete. I cant wait to here it run with its new header. It turned out good if i say so my self.
