The piping kinda looks like the heavy duty truck radiator hose I was considering doing my IC piping with. It comes out cheaper to buy mild steel pipes and weld up regular piping- that stuff is expensive. Designed to last a few hundred thousand miles on a bigass semi.

They have the equipment and the skills but I'd rather go to a shop that targets your type of car a bit more closely.
