Anyone here run the IMCO gatlin Mufflers? There are a handful of threads on them, but none that really answer my questions. I'm planning on running these with with Stainless Gen III 5" tails. What I like with these is they can be run wet or dry. My question is, has anyone ran these dry? When I have the tails made, I'd go dry so long as I don't make everyone on the lake mad. I'd also like to be able to use the boat in the evening, so not being the obnoxious boater is important. Any input is appreciated.

There nice looking with simple technology. Pricey but what isn't... Get what you pay for. I can't imagine any issues running dry considering the engines I've read that were in front of them. They use same basic design for off road use. Get some 1 1/4" SS baffle.
Now I see why you posted in regards to running dry. After some more reading some say yes many have said you need to find a way to cool them. I don't buy that personally. Check with Don Johnson. He ran with 1200 Teague engines so I would imagine they were run dry. Clamp on style I can't possibly see why not. You should pm DJ if no one post with first hand experience.

I've read just about every post on here about them. I agree that they can be run dry, the one thing I have read over and over again, is that they (any muffler) will look terrible if run dry. What I think I will do is have Stainless Marine install a small water dump in the tail to cool them, but have the majority of the water dumped overboard. Either way, I ordered them today, so we will soon find out.

Thats a good idea, but I'm not sure I have room about the pipes to run the dump. I'm also going to be adding a swim platform, so even if I have the room now, I may not after the platform is added. It is worth investigating though. Thanks for the idea!

I can't see those (Gatlins) doing too much wet or dry. I've run essentially the same thing, in the Borla mufflers for years and they have the advantage of being in a much larger case. They sound good, but I wouldn't say they are quiet. Personally, I find the price of the "Gatlins" staggering for what they are. After hearing my GGB's for the first time Saturday, I think I want to try the auger style next. I will say this for the GGB's though, they were stunningly quiet at 3k on the hose. For me, it's hard to judge what something sounds like on the hose though. The GGB's had kind of a poppy sound at certain RPM's. On the plus side, the GGB's are reasonably priced and seem to be very quiet in the cruising RPM range. It seems I've read positive things on the Gibsons, but I don't know how those sound or work.
