Look at the bend
mandrel bent alloy coated is the best pipe but there is a caveot
if it doesnt have the coating it wont last much longer an of the
bender strips the coating it usually rusts there

Stainless is no harder to weld than aluminised steel... both need a
mig. Nullarbor is probably OK but I'd suggest staying well away from
Nullmigs. ;-)

Aluminised steel from a reputable exhaust shop is the way to go unless
the original factory system is stainless, or part thereof (quite a few
are). Stay well away from it otherwise as it's expensive, ultra thin
and usually sounds shithouse.

Well my Corolla came standard with a stainless exhaust system and it wasn't
for show. It is also still on the car after 10 years and around 170,000+ k's
I expect it to see the car to the wreckers baring any mishaps with
obstacles.

As well it should
but you didn't go and specifically pay for it
it came standard

I haven't looked under the Prado to see what it's exhaust is made of
My old Ba's exhaust was 7 years old with 136,000 klms and showed no
signs of corrosion, it wasn't stainless

Not unusual for original equipment exhausts to last a lot longer than
aftermarket.
Tailpipes often rust out because they don't get hot enough to get rid of
the moisture which causes the rust, try fitting either a stainless
tailpipe or buy a genuine spare part instead of aftermarket.
People often buy aftermarket parts before checking genuine prices but
aftermarket isn't always cheaper, for example that last time I checked a
rear muffler for an 89 Honda Prelude is cheaper from Honda than from
Midas by about $50.00.
