Tips for installing axleback

[Pinchlite]

I have the Megan racing axleback along with new bolts,nuts,springs and metal (donut gasket)?

This all came with the muffler.

I dont want any opinions or comments on how its a crappy muffler but just some tips for installation.

It is winter here and will be doing outside.

I have ramps,floor jack,scissor-jack,air ratchet/sockets at my disposal.

What would be the best way to approach job.

I have sprayed the bolts daily for 3 days anticipating the removal of the bolts as I plan to do tomorrow...unless it would be better to bring to shop and have mechanic do it.

Thanks for any pointers/tips in advance.
