No, there is no "need" for a shop but only a glutton for pain will remove the nut in the manner you discribe.
Oh yes, no every home mechanic has the correct tools for this job.
And if he is wondering how to remove this corroded nut and bolt than is he up to even putting a new exhaust on, because it takes the right tools and is goyto be very difficult to put on without a hoist.

Oh yes, no every home mechanic has the correct tools ( ya really need a torch) for this job.
Maybe YOU would bust your knuckles. Not everyone is clueless. And yes I have all the right tools to take care of such bolt. If OP had all these tools he wouldn’t be asking how to take it off. Let’s ass7ne all he has is sockets and wrenches no torches, air compressor or air tools, grinders or lifts.
I’ve broken off plenty of exhaust bolts in such manner and never had any issues.
I got a few good chuckles out of reading some of the posts in this thread.
You don't need a torch. It is just a small bolt that is rusted. You could try spraying it with a penetrator like PB Blaster as has been mentioned and spray it a time or two each day for a few days to get it soaked in good. Sometimes it will loosen enough of the rust you can use a breaker bar or long wrench and get it started turning or as others have said just end up breaking the bolt off. Either way, it would be done.
I would probably just do as many others have already talked about and just get a side grinder with a cutting wheel and zip it right off of there in less time than it took most of these guys to type their response saying you will have to take it to a shop. lol I have broken loose or cut off so many of those rusted exhaust flange bolts over the years, I couldn't tell you how many it has been and I can't remember any of them being a problem. Just get a cutting wheel and cut it off, get a new bolt and nut and forget about it.
Clean the threads with a wire brush, then blast it with some penetrating oil. Drive to Lowes\Home Depot\auto parts store and pick up some bolt extractors. Let it cool off, then blast it again. Hammer the proper bolt extractor on and crank it off with a breaker bar.
Thank you all for this tips, ideas, product links and such. I'll update the thread with what I decided to do and how it turned out.
