Downpipe/Manifold Exhaust leak?

[joshhignight at techography.net (Joshua Hignight)]

Watch out for the studs and nuts on the flange. I just replaced my 
downpipe and two out of the 6 studs either broke or stripped. Not a 
fun or cheap thing to deal with. Also, the old O2 sensor is usually a 
pain to remove. You're probably best getting a new one if you can't 
easily get the old one out. 

peace,
Joshua

can't see where it is coming from, but I can feel the exhaust leak at 
a flange point between the exhaust manifold and the downpipe. Its not 
at the gasket, its in the 'shock thingy' that absorbs the twist of the 
engine. I'm guessing the downpipe fits in this shockabsorber and a 
gasket of some sort needs replacing. Since I cant get a good look at 
it and have never seen one before, I am only guessing.
