If I did, that means I got hassled and had a test done.

We are dealing with this at Lake Havasu also.

I think underwater is going to be the trick for new installs. Also, a cross over between the 2 tails is worth a couple db. For bigger hp you need one huge muffler to keep performance loss to a minimum if you are above water at idle with dry tails. I think the combination of underwater, cross tube, and wet tailpipes instead of dry will be the main answer to keep the hp, be legal for sure at idle, and be close to legal if a pass-by test is necessary. I know this won't be popular with the guys that like them loud at the dock and idling around!

What seems to be the biggest "unfair" part of this whole ordeal is that boats that are already manufactured prior to the enforcement ( I know some of these laws have been on the books a while) of these laws will have an extremely tough time, if not impossible time trying to figure out a solution, such as the 6" dry pipes on some of the high performance boats. They should have some exceptions with the amount of money you've spent to try and accomplish the sound requirements. Kind of like they do with a car that doesn't pass emissions. In Az. if you spend 400 or so and don't pass they give you a waver. Well if you spent a 1000 on mufflers and you still can't pass what more do they expect you to do? I guess they figure we have unlimited budgets to spend on our boats.

spoke with gibson, they dont have anything larger than 4.5" so that wont work. I guess the only answer is to spend $5800 on the cmi's like Get r' Done and wait for them, at least they will be close to legal, but the technology to get 6" dry exhaust on 1200hp just does'nt exsist right now, without backflowing the motor so bad and blowing up a 75,000$ motor.

Good question sean, I dont know why they could'nt, your right going from 5 to 6 does'nt help, still would be tough to tone down. are you going to hit the poker run. Call me if you need a ride, will have the newly painted rocket nortech cat, need a good throttle man.
