Just finished up a round of mods on a buddy's 2013 GT500. It has the SW's 3" o/r x-pipe connected to the stock axle back. I am replacing it in the next few days with a 3" Magnaflow exhaust. Also installed a 15% overdrive ATI harmonic dampener and JLT CAI kit with a Cobra Jet throotle body. Last mods are Steeda upper and lower control arms. I will shoot a video of the Magnaflow for comparison.
