The Saskatoon Sports Car Club is implementing the CAC/WCMA noise restrictions for events held at the Credit Union Centre. The criteria is as follows:

General Competition Rules, section 5.

Noise
K. An adequate muffler is required on all cars regardless of class or category. The criterion of adequacy is the noise level, regardless of any existing exhaust system. Any vehicle deemed to be excessively loud by the chief organizer will not be permitted to compete without modifications being made.

5.6. Noise Limit
Adequate muffling devices must be installed on all cars with a sound level to a maximum of 96 decibels [at racing rpm] unless there is a higher alternate noise limit for that facility/track listed in the Appendix E. In such cases, the maximum limit shall not exceed 103 decibels for vehicles in the Modified category but will remain 96 decibels for Stock, Super Stock and Street prepared vehicles. Organizers may apply to ASN for alternate noise limits if the facility/track requires or permits. Such limits must be sent out to all competitors in the Supplementary Regulations 60 days in advance of the event and must be posted at the site on the day of the event.

5.7. Noise Measurement
Measuring shall be done from a distance of fifty feet from the vehicle wherever safe to do so. The final decision as to adequacy shall rest with the Steward. Any vehicle deemed to be excessively loud must not be permitted to compete without acceptable modification being made, regardless of the existing exhaust system.
