Traded in my 2012 GT. I had added FRP power package with the GT 500 axle backs. Loved the sound of this exhaust. Looking at the Borla FRP axle backs for my 15. Just not sure whether the touring of sport would be closer in sound? Thanks.

 

I have the sport axleback and it's literally about as loud as stock. I immediately ordered the x pipe. I would go with the sport or touring catback. The suitcase resonator sucks the sound away.
