Are dry exhaust risers preferred over wet risers? If a have to pick which way should I go?

Dry are better but VERY loud!

Really depends on what you have for engine/engines. As Endeavour mentioned in most cases they are better however if you have basic stock engines the dry probably wont make you more power than that of the wet. The dry also gives you a wide variety of camshaft selection. Reversion is not an issue with dry. Post your cam specs and we can go from there. Dry do sound cool also....

As far as cam specs go I am running a Crane 731 N/A right now. I think I have my mind already made up on dry, but just looking for the thought of others. Thnaks!

You don't need dry with that cam. Plus you'll have the noise police all over you with dry exhaust. Unless you really need it, I'd stay away from it. The hassles aren't worth it.

No noise enforcement on the river here in Omaha. Mine are dry and dump the water in right before the mufflers. Brian, probably every time you have heard my boat, the mufflers have been closed. It is a huge difference in noise, especially at cruise speeds. Unless you have plans of going to radical cam, I would get wet risers. With dry, you won't have any protection against reversion caused by waves unless you add a muffler system.

Are you talking about risers that have a wet or dry joint between the base manifold and the riser??
If you are the dry is always prefered since there is no real chance of a wter leak into the exhaust and into engine if the joint gasket or pieces leak between each other.
With these type of exhausts there is no noise difference one to the other, just a lot more protection for your engine.
