It's a disease that is spreading. Below are my local tracks new regulations.
I haven't had my car tested yet but I'm almost certain I'll fail. And that is AFTER removing the straight-through pipes and installing twin Borla mufflers.
Screening Test - After a brief visual muffler check, a stationary test is undertaken. Sound levels will be measured 15 feet in front and behind the vehicle while the engine is revved at the maximum allowable rpm or the red line of the tachometer. The average should be no more than 100 dbA with no single reading over 104 dbA.
Pass-by Test - With the vehicle under full acceleration on the track, a reading will be taken from 50 feet. The maximum level allowed is 92 dbA. This level and standard is the most commonly used in North America and Europe and is where the entire industry is headed. Tests are valid for 9 months unless modifications to vehicle are made.
Cars and motorcycles that do not meet the noise criteria in the pass-by test will be black flagged and not be allowed to run until modifications have been made and a re-test performed to ensure compliance with the guidelines. It is the driver's responsibility to ensure their vehicle meets the noise restrictions that CMP has in place.
It's an f'n RACE car not a limo...
