I've already replaced my 2015 GT exhaust resonator with the Ford Racing X-Pipe. This added a bit more tone to my exhaust. I would like just a little more rumble, and I'm torn between the Ford Racing Touring axle backs or the BBK Varitune axle backs. The BBK have the adjustment to either have a full open muffler or a chambered muffler. My question, I can't find much concerning the BBKs has anyone tried them and what was your experience? Good or bad?
Thanks in advance!
