I have the S-Types ABs on mine and they sound great. no clip will give you a good impression. While I haven't heard the ATAK, I think it'll be too loud for me, especially with headers and X-pipe The S-Type is just right. If you're in the Los Angeles area, I'd be happy to let you hear the S-Types.
heres mineWhich sounds best on a 2013 5.0? The YouTube vids I watch I just don't know if they sound as good they do in person. I want a loud exhaust but I also want it to an annoying loud. Also I play on running xpipes and XR-1 long tube headers.
