I have the Nameless exhaust delete and there is a strong resonance at 2-2500 rpm and it is pretty bad with the windows up. Not too bad with a window cracked. There is another resonance at just over 4k, but that one is not as bad. Of course, we get what we pay for. Resonance elimination is not one of the design parameters of a muffler delete...
