Thoughts on this AAM S-Line Midpipe

[Samvindas]

This is my first post to the forum so I apologise if this isn't the correct way to post on here. However, I was wanting to see if anyone is running AAM's S-Line Midpipe with their nonresonated Short tails and could let me know how bad the rasp is if there is any. I'm looking to buy a used Midpipe and pair it with my short tails from someone who lives close to me for $650 and want to make sure that I won't be dealing with terrible rasp. I'll attach video clips sent from the guy I'm buying it from also, I just can't really tell over video if the rasp is bad since I don't really know what I'm listening for since I'm fairly new to aftermarket modifications. Thanks for read and hope to hear back from someone soon!
