The slots are for exhausts that are dry to the end and have a tube inside the tails that dumps the water.

I see where my 4.5" CMI dry tails need the 4" insert. The hard part is deciding on how long of insert and drilling the hole to hold them in.

Mine had a 3/16" hole on the bottom and with a pan head Phillips the hardware can't even be seen. The kits do come with 1/4" hex bolts but I put in the effort for a cleaner look. Are you just looking to knock a little bark off or have stiff sound limits?
The way they are constructed you can buy the longest ones and keep cutting off rings until you get the sound that you want. I thought I wanted the long ones but the 5.5" units are plenty for me.
