What standards does New York use for testing? I am surprised you were at the threshold of 90 db with your captains call on. SAE J2005 test is specific as to the conditions and distances of testing procedures. The only mufflers I have heard passed did so with water injection into the mufflers also. Do you have water or run dry? One friend here in West MI has Borla's on his Cig. It passes now and he runs dry. I do know we need to do more. They keep modifying the laws to make things more restrictive here also. I know both my old boats pass SAE J2005 but neither will pass SAE J34 which is currently being proposed. The new one won't pass either law! Let me know what you find out on the law.
