ericnolan661 Posted December 28, 2015 Report Share Posted December 28, 2015 Hi gang, This is the new Magnaflow cat back exhaust for the gt350. Not as raw and raspy as stock but more of a tunned sound. https://youtu.be/0N3D1pp0AMs Quote Link to comment Share on other sites More sharing options...
mikeljgt500kr Posted December 28, 2015 Report Share Posted December 28, 2015 If it sounds as good as the one on my '13 GT350, it will be a definite improvement, thanks! Quote Link to comment Share on other sites More sharing options...
svttim Posted December 28, 2015 Report Share Posted December 28, 2015 What does it do for the car? (other then sound) Do you loose the active exhaust Quote Link to comment Share on other sites More sharing options...
ericnolan661 Posted May 13, 2016 Author Report Share Posted May 13, 2016 Sorry so long to respond, life has been busy. Active exhaust is still functional and I was told by the guys at magnaflow that they ran a dyno and I picked up 14 hp. My butt dyno hasn't detected the increase, but it hasn't been calibrated recently. Quote Link to comment Share on other sites More sharing options...
