Is it worth anything performance wise to use the stainless steel DP that ZZP offers? Is the 2.5" big enough for using due to the fact that the rest of the exhaust is 2.5" anyway? Or is there a benefit to using the three inch even though it has to be downsized at the end of the DP? Remember, I am not doing major mods to this just want to be able to do the standard 3.4 package and get the most out of it. I will have a cat in this system and would like to keep my O2 sensors in the system as well. Thanks..Yes as stated above, throwing codes is bad........
