Has anyone turned stainless marine exhaust into dry exhaust? I talked to Joe yesterday and we think it can be a gain and he knew someone that did it, if anyone has... Got pics?? Gains?

You are not reverting... Is it worth the potential hassle from the water police? Is it worth the added attention which can often be negative? Is your boat going to be fast enough to justify being insanely loud or are you going to be "that guy" ?

All depends lol

Whats the benefit to increasing the length of the interior tube so it mixes approx 5 inches from the tip? It still baffles it but does it add power?

More power and less reversion, I am looking at going totally dry maybe for power possibilities

Im 100% Dry but I also have dampers when needed like coming in at late nights.

I was just going to make a post on your other thread and saw this one so it seems more appropriate here. I once dyno tested a set of stainless marine exhaust n comparison to dyno headers. I ran the tails dry. On a very mild 600 HP 540, the SSM exhaust lost 25 hp at peak rpm (5400) and over 40 ft. lbs. of torque. Mixing water will increase that loss. As power and rpm goes up the loss will be greater also. A good set of marine headers can pretty well keep up with standard dyno headers we were using.

Totally dry out transom? So to speak? Or mix at the very end at rubber hose connection? My tails are very long and mix right at transom connection

The test was totally dry. Just water in the manifolds to keep them cool. I would not expect water mixed right at the tip to cost any power to speak of.

Go dry and be that guy!!!!
