I’m not to familiar with dry exhaust systems. I know they have benefits over a wet setup. I’m looking at 2 boats and they both dry exhaust. I run on a lake that has noise restrictions. Would I be able to install turn down’s to help quiet it down a little bit?

Ayuh,.... Down-turns only quiet it when at idle, 'n just above idle,.....

Once ya break over onto plane, it tends to be open pipe Loud,....

Dry exhaust is insanely loud. Not even sure a down turn at idle Would help

What’s the best way and cost to convert it to wet?

You are going to have to provide some variables before we can solve that equation.....
1. why do they have dry exhaust in the first place?
2.What kind of exhaust and risers do you have??

If the engines are built for dry exhaust, or the exhaust was converted to dry because of reversion, then you are taking about a new cam, possibly lifters, pushrods, springs... then that will change the power, so now you are looking at prop work or new props.

If its just dry exhaust because the previous owner wanted it to sound cool, then your only going to be into it for a set of tips and buying your buddy with the tig welder a case or two of beer and a mid level hooker.

My neighbors love dry exhaust 😊

I have Dry Exhaust.

i have an aluminum swim platform and clamp on mufflers - the clamp on mufflers are the air activated kind, but they are inoperable. And stuck in the open position. I tell you this because mine are, for some reason, more tolerable than any other dry pipe boat I've ever heard. I also have big tube headers which I think makes it less raspy (as ridiculous as that sounds).

It's not terrible as the driver or front passenger, but it's a lot for people sitting in the rear seat to handle. If we are running more than a couple miles I like to wear some ear protection..... Idling isn't that much different in my mind. When you are backed into a slip and fire them off everyone in the marina will know you are leaving.

Two true stories:

1. I started mine in the front yard today and a friend that lives a couple miles across the river the way the crow flies texts me and asks if I just started my boat.

My neighbor 12 houses down was on a conference call last summer inside his house and someone on the line was a Motorhead and when I started it up he interrupted the call and asked my neighbor what the hell the noise was.


I would never buy a dry pipe boat just to be cool, that's for sure, nor would i convert one to be "cool". The cool factor of dry pipes is VERY limited, especially when it's your boat.....

I can’t answer why they have dry exhaust. My guess would be it’s for a performance aspect. I haven’t got into specifics with the sellers on what riser, headers are installed. Just looking to get some background info. By the sounds of things it’s not going to be a simple fix or an inexpensive change over.

Mine are swaged at the tip so kinda mixes as the exhaust leaves the tip. Engines haven’t been started yet so I don’t know what to expect. Would this set up be any quieter than if the water didn’t mix at all?

I think that will temper it some. Again, I think mine are tempered just having the inoperable clamp ons still bolted on.....
