I have been very happy with my Kooks, they make a fine product. Fit and finish was great and install went without a hitch. The kooks are more ¾ than full length and don’t hang down below the frame rails. I will have to pull them off next month when I do my TT install and I will miss the sound quality. I don’t know what the TT will sound like with a Bassani X pipe coming off the turbos.
