Sounds like he was lazy and just wanted to still keep your money.
On my g35 I accidentally sheared one of the studs off cat studs, the driver side that is pressed into the header. I tried to drill it out and gave up. Traded the car in shortly after that.
Point is, if they cut the bolt off, it wont be easy to remove that stud. But that is just my experience.
The exhaust shop that I deal with would use a cutting torch to blow the stud out and use a nut and bolt to install the new part. I don't do exhaust work anymore. Too old to be laying on my back getting a mouth full of rust.
I've read quite a few that have either used an air impact or had a shop use one, works well for the most part although snapping the bolt is more common when using impact guns. Always best to use plenty of that rust breaking mixture whichever method you choose.
Heeding the advice of you guys (didn't have the tools), I got em done at the shop for $120. Took them only about 2 hours. No headaches. No paint damage And no problems getting back my oem cats unlike that other guy on here haha.
