DIY exhaust replacement

Hey all, new forum member here. Been getting tips from reading this forum for a while, now I have a question I haven't found asked already.

Has anyone fully replaced a 120 series petrol exhaust themselves, or have a clear idea of any issues that would be involved?

My 2008 4l petrol Prado has seen a lot of beach use, and the exhaust from between the cat converters on each side is buggered. I can pick up a whole exhaust system in good nick (off a country use Prado) from the wreckers for about $400 ($500 with all 4 cat converters). Since most of my system is buggered, I reckon I may as well a spend the extra $100 to replace the whole system including all cat converters.
I'm thinking about taking a crack at replacing it myself, but haven't done any exhaust work before. It looks pretty straightforward, but want to know what issues I may run into.

Has anyone done this? And what was your experience with it?

Cheers

Undoing 14 year old exhaust bolts will be interesting,not to mention the dirt and crap in your eyes. If you don't have a hoist pay to get the job done.

It’ll be a slow but ok job without a hoist. Depends on how patient/broke you are. As mentioned before, some of the nuts may be pretty tough!!! You will need a good selection of ratchets/ring spanners and preferably a rattle gun for undoing (NOT DOING UP) the nuts.
Get the cats as well for a $100. Last time I scrapped some they where $80 each in scrap value
