I just posted the test results today -hope this helps. I really do love the sound of my HFM -but, anyhing sound better than the stock pipe.
As I indicated, if anyone in the Syracuse area has another aftermarket pipe, they can stop over and we can get the dBA for those also and keep a list.

 

I installed the muzzy and it gave me 50 hp..........hmmm that sounded funnier in my head.
