Is there a Cubic inch or horsepower limit to the CMIs?

I want to clamp something on that will provide a minimal amount of sound suppression, and also help prevent the possibility of water reversion....

I am basically looking for something like this I think:

I just dont want to muffle the sound too much.

I am positive that you are significantly over the DB limit even with the Gibson's. I would just leave them on and close them when rafting. Thats what I do. If you really want something like you say, then the Shotguns will be perfect.

They wont kill the growl, but they take the "bark" out at idle. Cops wont even look at you. Then on plane they are wide open.

We will help you out with price.

Thanks Brad.... I really like the concept to them... I sure would like to hear what they sound like at idle though.... I guess thats the draw back here, I need to take a guess and buy something and try it, and most likely stuck with them if I dont like them.... I'm not really liking that

I just picked up four of the cmi sound elimination mufflers on eBay. I plan to fire on of my 502's today out of the boat and will shoot some video of both without the mufflers and with. Hopefully this will give you an idea of noise level

I have the CMI's on my 600sci's and they are amazing. Super quiet at idle and still plenty loud at WOT.
