Your buddy has some bucks in that car of his.

Ti must be welded in a vacuum or under a complete inert gas field, then it must be etched or ground to prevent corrosion from ruining the weld zone.

Ti is actually a fairly cheap material - all of the cost is in the processing. Ti dust is used as the white sparkly stuff in fireworks, thus you cant just buff it or grind it.

Your jewlers cant just melt it down and reform it like they can with gold. Just like with the welding, once it reaches its melting point, it needs to exist in a vacuum or completely under inert gas field. You jewelers arent set up to do this kind of processing.

he used a factory zo6 vette exhaust as a donor. so really didn't have that much in it compared to what buying the raw materials. He made radiator hoses for it as well from ti, cut up some stock street bike exhaust and welded the bends together as needed, then just put rubber couplers on the ends to the radiator, and water pump. Pretty neat stuff, went in an ls1 powered 240z.
