To me the Atak just sounds louder, I went with the S-Type and the 60610 mid-pipe & x-pipe, this set up has the AFM valves and goes all the way up to the secondary cats without deleting them so I don't have to worry about emissions.
Here's some sound clips of mine, also have some more on my IG without background music (@gdgraph).
I think you'll be happy with either option. I am considering trading my S-type axle-back with someone who has the Atak, but I may do headers one day so it won't really matter because it will be loud no matter what, but for now I think it sounds great and with anything Borla there's no drone to worry about.
