Sound elimination clamp on mufflers. This way you can still take them off when you want to run with the boys. Here are a couple vids of one of my BB's with and without. Biggest benefit is no restriction when running WOT!

I dont know what your budget is or what you want it to look like...

A couple 90* elbows from a Y-Pipe through the prop only would probably make a significant difference if clamped with a rubber boot to your existing tips.

This would look terrible, but solve the problem cheap.

Most boat shops would have a couple of these laying around for next to nothing.

Drew Marine Shotgun Mufflers: they take the bark out around the dock and idling thru a channel, but open wide once throttles are down and no HP loss.

I have a set of Imco Mega Mufflers that I took off my old boat. They were on the boat for ~20 hours (I have to check my log to be specific) and are in great shape. If your interested, send me ur email addess and I'll shoot you over some pictures!

I've had them on 2 boats and can't say enough good thing about them, try them you will like the results

Set it up for turbos.

I have referred quite a few performance boaters to Aqua Power Ltd. marine mufflers and they have all called me back with fantastic results of quieting and no power loss or other issues. seems as though these puppies work!

I have Gibson mufflers on mine, if your wife is in that field I would go Captains Call, I found that even with the mufflers you still can't get it quiet enough for the ladies.

D!CK!!!!!

How about CMI's and dry tails....

Does anyone make a clamp on muffler that can be switched on and off?
