Currently have flow master outlaws for my 2013 GT and want to get rid of them because there is a lot of drone. I am looking into the Borla s-type and attack axel back pipes. Was wondering if anyone has any idea or experience with borla's because I am wondering if my flow master outlaws are as loud as the s-type or the attack I don't know which one to get becuse I want the borla to be equally as loud but not louder.

 

The Outlaws will be the loudest, followed by the Atak, and then the S-types.
