Sold Single

You can solder it directly on, or should you prefer it removable:

Solder-on/ Spingload:

Those require some minor soldering.
Slide the flextube over the bend or silencer entry port and mark where you want the flextube to stop/end - or it may come to a stop by itself.

Grab a large enough washer and cut it in half. You now have two “Rainbows”.

You solder one half of the washer to each side of the bend (top and bottom when viewed from the side), right where you want the flextube to stop.
Now apply Permatex or other heat resistant sealant product to the bend in good amount and slide the flextube in place

Grab two springs and two pieces of wire.

Mount the one end of the spring to the washer, tie the wire to the other end spring, pull the spring towards the flextube and wrap the wire around the coils of the flextube as and where needed to position and maintain spring pull.

Repeat on the “other side” of the bend, you now have springs on “top and bottom” pulling the flextube in.
