Hi Greg,

I used POR 20 when working on my '93 S4.  When correctly applied (per
instructions) I think POR 20 is great stuff.  On my car I ended up using
POR 20 on the sides of the head, RS2 exhaust manifold, RS2 turbo and
waste gate.  The car has been back in service since September 1st and
the POR 20 is holding up just fine to the under hood heat.  I'd think if
it can cope with the manifold and turbo the exhaust system would be fair
game as well.
