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?

As for the rest, why did you buy a GM product to
begin with?
The only reason I ever bought a GM product was price - and it sure
didn't translate to low COST.

You were an automotive service manager and you
didn't know better?
