Not a real good idea to have ANYONE on the swim platform if you're backing up:eek:

I NEVER had ANY reversion issues and they sounded GREAT on plane as well as cut some of the interior resonance....

The only thing I didn't like was the lack of "dock presence"... sounded little better than a Sea Ray at idle, (82 db at idle) but I suppose I could've cut them a bit shorter to get more sound out of them......

I also wanted to keep from bubbling directly under the swim platform and keep soot off the transom, so I went with more of an angled design. GGB built these turn-downs to my spec. They're bolted onto HPI mufflers and have DMP internal flappers. The biggest hurdle was clearing the center turn-downs with the tie-bar in the trailer position. Imco fabbed custom saddle mounts to get the tie-bar farther back. I have not had this setup on the water, yet. But, here's how it all turned out.

It made the boat legal also with law enforcement here compared to being WAY over the limit before.

Mine were not Gibson they were custom made by CMI since Gibson did not offer 5" turn downs.

Here is a vid from a run where you see the boat starting as well as a bunch of pictures. I have sold the boat to Japan but still have the turndowns, they will likely go on to the MTI if we can make them fit.

I sure wish I had known GGB was doing that when I bought mine a few years back. They are out of business now right?


Thanks

Can someone tell me why these would not work? I am just not spending $500 + for a 4" single wall pipe with 1 bend. I do not plan to use them often.
