: I'm getting ready to install the 3rd set of exhaust manifolds and I understand there is a stainless steel set that came out in the mid '80s or so. Does GM still have these and if so, any part numbers? If not, any recommendation on aftermarket stainless steel pieces or should I just stick with the old cast iron ones?
