Making your silent exhaust temporary

I am in need of ideas to make my through hull exhaust silent just for marina use. I am going to emerald coast poker run and the condo I am staying at requires silent exhaust to park your boat there. Anyone have any ideas to shut it up temporarily. I have 4 inch flat tips.

If you have 4" thru-hulls, you need the 3" inch PVC 90's and a short section of soft-wall hose. But it does work.

Or get the real Gibson turn downs. They are the most effective muffler that I have heard, no moving parts and wide open once on plane.

Measure the O.D. of your exhaust tip and then go to your local plumbing supply house and buy two rubber couplings or "Fernco's" which will slip over the exhaust tips and tighten down with the worm clamps then get two DWV "street 45's" to angle down and how ever much PVC pipe you will need to reach underwater. You will need some PVC cement but it should all hold together well enough for a slow idel out of the marina.
