GGB turn down
#2
I dont think anyone sells a turndown specifically made for GGB's. When GGB was still in business, a friend had them build his mufflers with turn downs welded on. However, during what I think was his second year of running them, one muffler cracked at the weld, sending the back of his muffler and the turn down into the drink. Unbelievably, someone he knows, recovered the piece a year later while scubadiving. Gotta love fresh water. If that were here, it would have turned into a reef in a few weeks.
I have a set of GGB Extremes, run them full dry. They work well but have noticed mine have cracked around the welds of the casing. It has become a normal maintenance for me to weld the cases back together as the cracks form. My advice to you, if you need trun downs, be very careful. Keep a constant eye on the cases for cracks.

We can them made to your specifications. The standard is a
4" dia with a 12" x 12" Elbow.
If you know where the waterline is on your boat add about 4" to get the exhaust into the water and draw a sketch. We can get you a quote from CMI.
