IMHO, it did not make a lot of difference in sound. It is slightly more raspy, but really not a big difference at all.
I felt no difference in power at all. Hell, they are basically just a straight pipe with some hole in the walls for baffling sound. No restriction for flow in them, so I would not expect any hp gain or loss.
I surprised, from the first couple of videos I noticed a good difference in sound. I'm going to do the resonator delete as soon as I have some free time on my hands.
