Just a little insight to the noise ordinance. Don't read into this that you will not have a problem or vice versa, purely just an FYI. The first time out this year I had to get my trailer weighed (new to me boat w/out weight slip) for registration purposes. I had not had the chance to get the boat sticker yet either. I went to the ramp for the simple purpose of putting my boat in the water to take the trailer to the scales at the Flying J. When I went to the ramp the DNR was sitting at the side of the ramp, primarily looking for people w/ expired registration. I approached the DNR and told him my story. He was very nice about the whole deal and could have just told me to come back at a latter time w/ proper registration, but since it was Saturday & I would have to wait until Monday he didn't do that. What he did was tell me if I pass a full inspection, he would let me put in for a few hours to take care of the trailer. When he got to my exhaust (straight exhaust), he asked if it was o.k. or not. I admitted I had it put on a few weeks prior and it was louder than most boats, but my mechanic used the same materials as the Baja factory. He simply replied oh, o.k..
Moral of the noval.....Don't be mean or do anything that gives the DNR a reason to ticket you. I think they are pretty level headed.
