Flowmaster American Thunder NPP community reviews

I've seen a few forum posts about this axleback, but I'm just curious on how many people have it and what their feedback is. I'm on the fence between this and the borla S type with no valves, similar pricing between the two. In videos they seem significantly louder than the stock NPP. What are your guys thoughts about them? Deeper sound? How they sound with headers? Drone? Valve rattle? Stealth mode loudness? Etc. Thanks for any feedback. First post on here btw
