I did it. I got a 5'' turbo back magnaflow and a quadzilla dpf delete tune stacked with my six gun. I fired it up and it sounds awesome. I took it for a short drive and I am amazed by the new throttle response and power. Thanks everyone for the info and support. I could not be more excited to drive my truck.
By the way, I got a great deal on the exhaust from Tyler at meyerperformance and not to mention tons of tech support. Thanks Tyler
