Crankcase breather question

I'd also like know, if anyone can answer it, why you can run an evac system if you run mufflers. Also, do glasspacks count as mufflers?

I ran two of them into the TTI collectors with full length 3 inch duals and TTI supplied Dynomax mufflers. They pumped a lotta oil into those mufflers. That made me think; man if they can do that, then I get how the headers can work thru the overlap cycle. So then I retarded my cam to split overlap, to take max advantage of that. Carrumba!

As to your question; if I guessed at the answer, I'd only be revealing my ignorance. But I think there is a lot more going on in the exhaust "system" than I will ever understand.
But one thing I can say; I've never been sorry I chose the dual 3inchers. Even my 318 smogger winter engine liked them. And the one time I tracked the car with open headers, by seat of the pants, I noticed no power-difference as compared to full exhaust on the street. Course the track I went to had no starter box, and the runways were holier than regular streets in town.So IDK;can't say.
I only took the pipes off cuz they weigh 72 stinking pounds, and they are rigged to practically fall off the car.
If you learn the answer elsewhere, I'd like to know too.
