I do have a smart phone. But don't have a DB reader on it. Even if i did, i dropped it enough to where the speaker barely works on it. So i wouldn't trust the sound recorder on it.
I will say this. I had a 2.5" exhaust with a resonater right after the down pipe and a 2.5" muffler. I then built this exhaust which is 3" the entire way with no resonator, and this muffler is 3" also. And this exhaust is far deeper and much quieter.
No I don't have any hard numbers with charts to prove. But out of the 20 something mufflers I had on FC's. I would choose this one any day.
