<E28> Exhaust - catalytic - recommendations?

[khensley@xxxxxxxxxxxxxxxx]

On my 1985  535i  I need to replace the exhaust from the end of the 
exhaust manifold back.  What's there has rusted out.  For the last 
"half" of the exhaust I plan to use a stainless steel system 
recommended by some of you.  For the first "half" - which includes 
the catalytic converter - what do you recommend?  And what about the 
oxygen sensor?  Thank you for your time - private replies are fine.
