Installing Pro 1 Exhaust System help?

[ProjectM96]

Hello everyone, I just bought the Top Speed Pro-1 Exhaust System and secondary bypass pipes for my 2000 Boxster.

Using regular jacks and jack stands, will I be able to do this job with normal basic tools from a $35 tool box? Or will I need a pneumatic air gun to open the bolts?

Should I expect the bolts to be stuck? They look very rusted. I counted 18 bolts to open through visual inspection. There might be two I missed.

Any directions on how to install? Do I need to disconnect the battery when handling O2 sensors? Do I need to remove any suspension pieces to remove the test pipes? I also read somewhere once before that the rear bumper needs to be removed in some cases to do the installation.
