Exhaus cost

Anyone work in a shop and could give me a rough estimate for the following scenarios:
'83 Caprice
1- cat back - including parts
2- muffler and tailpipe - including parts
3- muffler only (just labor to install the muffler)


Thanks

cat-back with a flowmaster was $350 installed for my '89

I was quoted $290 plus tax last year for an '84 Caprice, included everything after the cat. I did it myself with $105 worth of parts from Auto Barn.
