Default Muffler back pressure

Hi,
I need to drill and tap my muffler on my four stoke to get some pressure to the oil tank on a 120 OS....Where would I get the most pressure from on the muffler?
Thanks.

I believe closest to the header, but someone else should be able to give you a definite.

I don't understand how this is going to work. Do you expect to have enough pressure to just push the oil into the muffler? That will never work. You can't use muffler pressure to drive the oil into the muffler. You need a pump.
