Looks like youv'e got the exact opposite problem to me ! Maybe there's a rule
for conservation of torque like there is for energy. All the torque that
I'm losing
from my downpipe nuts ends up on yours. (Oh no ! Here we go. Another torque
thread. Me and my big mouth)
Someone wrote to me saying he once had some downpipe nuts welded to the pipe
to stop them coming undone. (I shall withold his name to protect his
reputation)
Maybe you should have a careful look for signs of Marcus's^H^H^H^H^H^H^H^H a
welding torch.

... and get the remains of the studs out of the manifold. You could try sawing
off one side of the nut, close to the threads. Or use a nut spliter. Or
take the
manifold plus downpipe to a mechanic's shop and ask to borrow his air powered
wrench.
Good luck,
Julian.
