Drill a 1/4" hole, a couple or a few inches in from the end, on the side next to the bike so that it does not show. Not too far in or you will have difficulty installing.
I used a washer that is about 3/4" OD - it just happened that in a huge box of spare junk there were two the same about that size.. The size does not matter, nor does the ID size. It just has to interfere with the flow.
A lot of guys use a thumb screw rather then welding a washer onto a bolt.
They are tuneable by slanting the washer. I kept mine straight up at 90` to the flow. Some guys prefer 45` angle.
