With the Full Evo system, you might be right at 92-93 db. We will be testing Evolution system this Friday at Laguna Seca track. They are very strict about the noise levels so it would be a good chance for us to check it.
Feel free to PM me if you have more questions.
If you can fit in a 3/4 rev at 50 ft measurement during your testing, that would be much appreciated!!
