91 corolla.gathering my info to repair a Muffler exhaust system. I may not have all the tools to do the job

I do not think it is that hard? I guess fro m the cat, to the rear is the issue. pipe is old. I will have to see what is the best way possible to attack this. I do not want top dollar parts. enexpensive is best for my need
any suggestions, parts to get help. thanks

If the Muffler is welded, go to a shop, if it is clamped be a simplier job Personal info given from a professional. thanks FISH thanks you can still do the work but want welding its best to shop it.
