I have the GT500's on my 2011 GT and I have to say that this video does them no justice. The stock setup almost sounded better to me. In person, the GT500's are awesome. After a while though, the bug hits you and you want more, so I put the GT500 over the axle pipes on the car which delete the resonators. That's when these mufflers REALLY woke up. Still it didn't quite feel complete, so I ordered the Boss 302 side exhaust, and it came in today. Going to install it mid week probably. I'll post a video when I put them on.
BTW awesome '13!!!
