The open end cap that we sell is in the shape of an ice crean cone with the end cut off of it. If you just drill a hole you won't get the same performance.

along the lines of the original question, how many discs does the open end take the place of in the ids mufflers? at what point does the number of discs no longer give you increased flow when using the open end cap?

The open cap for the 3" has a center hole of 1.25". It is equivelent to about 8-9 discs.
In the 22 disc range you are starting to outflow the core and becomes just hanging weight. With the open cap, remove 8-9 discs and your there.
