Well, actually, smoking in any form is pretty manly. Think about it: you are ingesting the product of FIRE, MAN'S EARLIEST ALLY AND DEADLIEST FOE, ONE OF THE FUNDAMENTAL DESTRUCTIVE FORCES OF THE UNIVERSE. And you're just sucking that shit down. So fucking manly. And on top of that, you might get cancer from it. Extra manly points.
Cancer? "This is me giving a fuck."
So yeah, while the simple act of smoking is quite manly in and of itself, the use of a pipe bumps up the manliness to untold levels. Pipes are just awesome, end of story. Even if you're filling your pipe with some of that "funny stuff" the hippies like so much instead of good old fashioned tobacco, I ain't gonna judge. Pipes are manly and so are you. Happy smoking.
