Looking at my new 2013 Ram 1500 4x4 Outdoorsman, one of the stock pipes is crushed to half it's size under the other where they "y". So no, the engineers have not made any improvements in this regard over the 2012 mode. Then looking at the stock air filter, it seems to be somewhat restrictive as well. I am thinking about a CAI, y-pipe, and muffler combo to start with and maybe a TB, but I'm not sure I want to drop $$$ for everything installed when I am not sure I'm going to see and power or fuel economy not to mention risk my 5 year warranty. Can anyone say if these mods will show any gains either way so long as I do my part when driving? Is there any significant risk to the truck if I were to install these mods without a tune? I would think that changing the airflow so dramatically would be damaging to the timing.
