I had the Librands sports silencer on my 2015 GDI & must say it added a vereeeeeeeeeeeeeeeeeee deep note to the exhaust sound (almost too loud - imho)
.
So IF you opt for the Librands specify the "calmer" of the two versions offered...
The "oumph" was increased - well: at least the feeling of...
+ it seemed to rev freer all over.
The best solution is to fit a full system, only then you might get significant imporvement on performance ( AND noise...
