[C320-list] Trident hump hose for 2" OD exhaust hose

[Walter Schaffer]

I'm having my fiberglass aqualift muffler repaired (again), and I'm trying to find a Trident hump hose to fit my exhaust hose to eliminate some vibration.
My exhaust hose for Yanmar diesel is 1 5/8 ID and I believe about 2" OD.
West Marine and Defender catalogs only show 3" ID. I believe this size will be too large?
Anyone know where to get a smaller hump hose to fit my 2" OD hose?
