New Noise Law & Mufflers

I am just looking to make sure whatever mufflers I change to are the best available so I do not ever have to replace them.

What are New York's laws on noise? Are switchables legal or is it like Ohio as I posted? I have some RC boats that even those who like noise think are obnoxious.

switchables are not allowed, I even took them off my last boat and sold them. I agree with the rc noice mine it bad , but if I can run my weedeater and the neighbor doesnt mine , Then he can listen to my rc with the weedeater engine. It will be interesting to see how the summer goes. Why can't we all just get along.

we have tried all the exhausts out there on extreme blower motors from 750-1200hp, dry/wet without any success, even the cmi's, the cmi's also are bad for spring failure, have now seen it on 2 boats here at loto, we have a great source for any custom configuration for polished turndowns, we have been able to easily make all the boats we have done legal, the last was a triple engine 900 hp blower motor application , which was 104 without 83 with at idle, we also made them so you could put an insert in them if you want to be fully protected on a moving tests, the most economical way to make them legal so far is this method we believe,

Wiggler, we were down there last weekend for the poker run and I was trying to find your boat. My dad called me and asked me to look at it to see your set up. I did see a big cruiser with turn downs on it at one of the stops and it looks like a great idea, but what about reversion, what type of cam are you running , we have a split pattern .710, .690 lift roller with a 108-110 lobe seperation, on naturals. any type of info would be appreciated . we won't be ready for this year but will be in next year with the new hull design .

no chance at all of reversion, the boat is out of the water, trying to sell, had it on 54. if you are concerned about reversion a simple hole inside the transom on bottom of tailpipe, and transom exit similar to nortechs stealth is an easy fix, my application just has too much angle and downturn for that. have to talk to my engine guru to get you specifics on my motors, sorry can guess but will get you exactly if you need it, thanks jim
