:wink2: Howdy everyone, I am supposed to receive my new 2017 3500 6.7L with the Aisin around the first of December? I am not going to do anything that will void the powertrain warranty. I am however thinking about changing the air intake with a AFE Pro 10R Momentum HD Stage 2 system, which from my research seems to be the best with proven results. I also am thinking about changing the exhaust from the DPF back, with a Magnaflow 4" Pro Series, with a 5" intercooled tip, all stainless, which also seems to be the one with the best results and the look that I want. I know that the results aren't going to be huge, approximately 15 HP and 22 ft.lbs of torque, according to the manufacturers? It could possibly help the MPG and the EGT numbers? This is about the only "performance enhancing" things that I can do, without affecting the warranty. Please let me know what you Cummins veterans think, as this will be my first Ram.
