NOISE TEST
1) The Report allows for 2 Tests before receiving a Defect Notice then a "RTA Suspension Compliance" where your car will be taken off the road if it does not pass

2) Exhaust System diagram

3) Noise Test @ 5700rpm (limit 90dB) and Throttle-off/Deceleration. 3 Consecutive results must be under 90dB all up and averaged... although i'm sure this is vehicle dependent

4) Tester Notes... consists of any comments on things such as non-compliance items, modified items that need to be reverted to oem, etc.
