Acttually, ( i asked demon Before) if i remember correcty, the resonator is for sound only with very little restriction.
the main restiction is in the precats and the actaull piping diamater itself. So i feel you will only get a rasping tone. Now some people have had experiencd sligtly diffret leves of rasp..some tolerable and some not.
I honestly can;t tell you if you would like the sound, because its to personal prefrence, but i cna tell you that it will get lounder and theres a good chace you will get rasp.
