[QUOTE="vennom, post: 4089435, member: 17173"] Just got done doing some research after a buddy of mine got an exhaust ticket and here is what i found. The old exhaust law I found in an old post [URL="http://www.svtperformance.com/forums/showthread.php?t=224708&highlight=rcw"][/URL] RCW 46.37.390 3) No person shall modify the exhaust system of a motor vehicle in a manner which will amplify or increase the noise emitted by the engine of such vehicle above that emitted by the muffler originally installed on the vehicle, and it shall be unlawful for any person to operate a motor vehicle not equipped as required by this subsection, or which has been amplified as prohibited by this subsection so that the vehicle's exhaust noise exceeds ninety-five decibels as measured by the Society of Automotive Engineers (SAE) test procedure J1169 (May, 1998). It is not a violation of this subsection unless proven by proper authorities that the exhaust system modification results in noise amplification in excess of ninety-five decibels under the prescribed SAE test standard. A court may dismiss an infraction notice for a violation of this subsection if there is reasonable grounds to believe that the vehicle was not operated in violation of this subsection. This subsection (3) does not apply to vehicles twenty-five or more years old or to passenger vehicles being operated off the highways in an organized racing or competitive event conducted by a recognized sanctioning body. In a nutshell it states that your exhaust can be modified but it cant be more than 95 decibles as measured by the SAE testing methods. The new law: [URL="http://apps.leg.wa.gov/RCW/default.aspx?cite=46.37.390"]http://apps.leg.wa.gov/RCW/default.aspx?cite=46.37.390[/URL] (3) No person shall modify the exhaust system of a motor vehicle in a manner which will amplify or increase the noise emitted by the engine of such vehicle above that emitted by the muffler originally installed on the vehicle, and it shall be unlawful for any person to operate a motor vehicle not equipped as required by this subsection, or which has been amplified as prohibited by this subsection. A court may dismiss an infraction notice for a violation of this subsection if there is reasonable grounds to believe that the vehicle was not operated in violation of this subsection. The new law in a nutshell, you cant have a modified exhaust that is any louder than stock. Apparently flowmaster catback is loud enough to warrent getting two tickets in 3 days making the trip from pullman to Seattle. . .under the speed limit. This is so annoying and frankly a pain in the a$$. [/QUOTE]
