2 small holes at bottom of end can ..

[Fazerider]

just curious fazer rider, does the left hand cone line up with the outlet hole at the end of the exhaust?

reason: sharp spike hammered straight down the length of the exhaust.

Well, sort of. That is, the cone is central and so is the outlet, but the outlet pipe is at an angle so your "tuning" mod (if that's what you're hoping for) will have to go through the side of that pipe in order to stay central. Chances are that the force needed to drive a spike down there would end up ripping the welds apart, particularly the spot welds to the mesh. So you'd end up with a can full of mangled metal that sounds bad and performs worse. :lol
