They do have the two holes on each can

 

Phil, those are the ones I had and didn't like. However, sound is totally subjective and you may like them once out on the road.

That's the same ones I'm running. HD part #64903-99 (discontinued). I really like them. Quiet enough just putting along, but they definitely let people know I'm there when I hit the throttle. And yes, sound is very subjective.

 

u can still get them supertrapp se
