[V6-12v] Exhaust manifold studs (between manifold and cats)

[James Whitehouse]

Eyvind,

I've only removed manifolds with the engine removed from the car, no idea how easy it is to remove them in situ, but mine weren't particularly seized on, if that helps.

Frank, if you replace the studs with bolts, how easy is it to detach the cats after that? With the original studs, you can just undo the nuts from underneath the car with a long extension, I would imagine that with a bolt and nut, you would have to get someone else above the engine to counterhold the bolts?

I drilled them out and used a stainless steel bolt instead. A lot simpler 
than trying to extract the stud and re tapping.

I removed the exhaust system on my mom's '96 A6q yesterday. The cats had 
disintegrated and the bits were blocking the exhaust. Of course, after 11 
years of salt, the studs between the manifolds and cat pipes were just a 
mess. 3 snapped, I got the nut of the last 3. Now, they are pretty bad too - 
almost no threads left, so I want to replace all of them.

Anyone done this with the manifolds still bolted to the engine? It looks 
*very* tight to pull the exhaust manifolds from the engine, but that way, it 
will be easy. Is it really that hard to pull the manifolds?
