Motoworks has two options for the sound. The standard pipe is right at 99-100 db. This has no restrictions. We also make a quiet pipe that we run in WORCS and the AMA/ATVa. It is right at 96.5 at 4500 rpm and 95 db at 2950 rpm. There are three different cores that we run to get this. We are also running very fast motors. The stock motor is considerably quieter with our race pipes. We have people in WORCS passing sound at 98db with our standard pipe and no core. I hope I have answered your question.
