He went the Donkey Dick way and now they are cracking down on the noise level at speed I believe. Hopefully he will come on with an update. I am trying to find out everything I can because I only want to modify once.

Hey Bob I was just rattling your chain bro... You guys put on an incredible run. Food, drinks, entertainment, etc. was incredible. I was more than happy to donate to your boat club.

Looking forward to having my boat at your next run.

Last summer I was busted for being too loud. Twin 1400's. I even have a DB meter to test mufflers. 3 sets later I bought some CMI's mufflers and they tested at 90 DB my meter and passed the required test by the Sheriff's water patrol. Illinois is 90 db. Once you get a ticket you are not allowed on the water until you pass. THE CMI MUFFLERS DO WORK!

Re: Can any mufflers pass 90 decibels ?
 

Have you run any tests at speed? Currently Wisconsin law is 88 db stationary, 75 db at shoreline, and 86 db passby. The passby is at WOT under SAE J34. Michigan is threatening to pass the same as Wisconsin and legalize the "Noise Gun".

This is a clipped section from the current Ohio law and a similar proposal would be included in Michigan's. I believe CMI's and Shotgun's would not be legal under this rule. The guys in Ohio have mostly said they don't enforce it there unless they get a complaint.
No person shall operate or give permission for the operation of a powercraft on the waters in this state that is equipped with an altered muffler or muffler cutout, or operate or give permission for the operation of a powercraft on the waters in this state in any manner that bypassed or otherwise reduces or eliminates the effectiveness of any muffler or muffler system.
