is there a standard to this procedure?
or is it all custom welded "on the fly" to what you want?
is cutting the exhaust hole on the left of the bumper harder than a jig saw effort?
how many people have twin (quad!?) exhaust?
how does it change the sound of the car?
i really don't like sewer pipe sized exhausts... so would go with something only slightly bigger than stock... twin exit... both sides... (ooh side pipes - would love side exit!)

No standard, lots of people have done it already in various formats. Can either have one muffler box at the back and the two pipes coming off it, or smaller twin mufflers, or whatever you want to use really.
Some inspiration for you.

Here's how we did ours underneath, and how we did the cutout:
It's not the tidiest cutout but did the job.
This is how it was done before adding the new quad tips.

Neither of us have ever actually put the quads on yet, but both of us have been meaning to.
We both have the same rear section too.

Nah just chuck a 6" tip on each one.

My dual setup is pretty much an aftermarket MR2 (SW20) muffler.
Worked well for me with a VS rear bar.

I created my cut-out by making a template of the curve and mirrored it.
Cut out within the line the section, then used a heat gun and two small wooden blocks (covered in leather) to mould the curve to what I wanted - ie, the opposite of the other side.
