Eisenmann Muffler Install...help

[MBMW]

Does anyone have any tips how install the Eisenmann mufflers, where to cut the stock exhaust to get the tips flush with the bumper?

I just got the muffler and there are no instructions, called the dealer and he said there are no instructions per say instead he sent me pictures.

Can anyone help please as I don't want cut in the wrong place or do multiple cuts.

Thanks
