I almost went down the same path as I did with the 116 kit and de cat my bikes rear exhaust pipe, until I was about to get it fitted only to listen to a bike at the dealership in Sydney that had the decat and cams with the high flow filter as mine has. It was so loud I knew if I did it ,that it would not be long before being defected for noise . A mate got pulled over on his Harley this week the Highway Patrol guys went all over his bike for exhaust ,ape hangers and filters they told him they are doing blitz on bikes up to December . The thing they did and was incorrect, was doing the noise check on the road side even through they went to the trouble of setting the mic at the required 45 degree angle and less than a meter away from the bike . But the law says it should be done in an open area where there are no buildings for the noise of the exhaust to bounce off. I told him to take them to court over the noise level check . But his bike has no cat so he ,is going to have to cop it although, he has to now go to the hassle of getting new exhaust that complies, change his handle bars from the Ape hangers to handle bars that also comply. Funny he has a open filter like mine and they did not worry about that too much ,but mentioned the EPA would want that changed to a covered filter due to emissions and noise induction . OMG I must have had someone looking over my shoulder before I put the exhaust with the de cat on and was telling me to leave the bike as it is. Thanks god I did not go ahead with it so now if I get pulled over they can look as hard as they like. I don't know how you guys in the USA get away with the noise levels by doing the decat and then put louder slip on pipes on your bikes. But I understand a lot of the time we all take a chance and deal with it if anything happens.End of rant for today lol.The sad thing is all the defects are recorded and once he gets them to comply and has them cleared they note all the fixed areas and take photos of the pipes etc and log that against the registration of the bike so the police only need to pull your details up on the police cars commuter if you changed it back to what you had then the fines increase and possible cancellation of your registration . The police don't even have to stop you ,just by driving past and checking your bike against their computer is enough to either be pulled over or have defect notice sent too you asking for you to present you bike for an inspection.
