I am running two of those near where the stock location would have been in the factory mid pipes. The offset on them allowed me to squeeze them into the super sprint mids.
I ran with no cats for a bit after I put the header in but there was a very irritating rasp around 2k rpm that was driving me nuts. After the cats the rasp is gone, deep tone, I am very happy with it. It's not the quietest car on track... but it certainly isn't the loudest. I don't have a video of it with the current set up though, sorry I can't help.
I cut out the resonator & cutout the muffler, trying to find where the rasp was coming from (it was just a resonance thing) and both of those were not options as they were embarrassingly loud on the street (IMO). The setup is very streetable.

Nice... do you think the Magnaflow are more efficient than the stock secondary cats.
