I have the Gen 2 GESI and I would tend to agree. With the valves closed it’s not bad at all - open it roars but not stupid. I really see no reason to go with an aftermarket axle back with this setup. I love it.
Also no real rasp either, the cats seem to prevent that sound that you get with off road pipes and NPP.
