Stripped 14mm nut

[240SXedUp]

Im putting on my new exhaust and every bolt came off with ease except the last 2, the ones bolted on to the cat. I used a cheater bar for one and ended up stripping it. Ive searched this and there isnt anyone really in my predicament. I dont have a blow torch, I dont have a dremel. What should I do?And getting a tool to adjust to the strip wont neccessarily mean I can get this nut off. It is really rusted on there tight.I may be able to find a friend who has a dremmel. If so, what do I do. I really dont want to spend 50 bucks to have a mechanic put it on since my only problem is 2 ****in nuts.

I know this probably doesnt belong here. But I figured you guys would know the most about the subject

soak it with rust penetrant for a couple hours and try again. worst case you will have to drill them out and use a nut and bolt through the stripped holes.

Ok, me and my friend hacksawed the rusted nut off. Took us about 15 mins but it fell off. Now the bolt is still jammed in the hole. Anyway to get it out?

drill it

yeah, drill......I used new nuts and bolts on all of my exhaust work on my focus....except the header to head bolts/studs....works like a charm, just drill that mofo out
