good god go down to merriam-graves and get a little 110V mig machine... about $400 should get you the welder and your very own gas bottle. Go to the local town dump and find some metal scraps, go home and spend about 2 hours teaching yourself how to weld. Then fix your exhaust. Congrats, for less money than it would have cost to pay someone else to fix your car you just got a very useful machine and the skills to keep your car alive indefinitely.
