I ran the pipe but did not really try and compare it but I did see some differences. For me it was a good pipe. What I felt from the pipe compared to when I ran a GO O801 and JP3 was that it makes the powerband really wide and linear. You do not have the bottom end snap really badly and do not have the abrupt change from mid range to top end. It is just a very smooth pipe from bottom to top. Biggest thing I noticed is the pipe is QUIET, I mean REALLY QUIET compared to others.
