Not true with my exhaust system. The stainless steel exhaust has never
once been cleaned and it is now 16+ years old, and in the rust belt.
Surely GM could have used the same stuff in the brake lines, which is
magnitudes more important than the exhaust system as far as safety goes.

So you never go through a car wash?

Never, at least not with this truck.

And what pressure does your exhaust have to
withstand? What pressure do your brake lines
have to withstand?

The break lines have no problem withstanding pressure, until they RUST!

sigh

Never occurs to you that the stresses something
needs to withstand affect the choice of alloy to
be used, does it?

Of course, which is exactly why brake lines should be made from
stainless steel and not from crap that starts to rust 3 minutes after
installation.

Which specific alloy of stainless steel should
be used and why that alloy and not some other
alloy?

One that makes them not rust out. Your local stainless steel
manufacture will gladly help them out. I could tell them but no reason
on earth they can't find out from a better source.

Engineering is always a compromise.

Perhaps a few $Billion in fines would help them compromise on the side
of a safe braking system, rather than $billions for fudging on MPG...
