With all these metals experts on here can someone explain to me how the $100 mild steel hedman headers that are rusted and look like hell havent fallen off my 46 ford? They've been on for 15 years and have been through many heat cycles. Are you going to tell me that mild steel is better than supposed Chinese steel? I'm gonna take a shot in the dark here and say my OBX headers will outlast the mild steel fenders on my car.
Btw, china produces 44% of the worlds steel.
