another question I'd like to ask is about the exhaust. I like to hear my vehicles.. my truck has 4" and my Hawk has 3" with electric cutout.. so it's safe to say I can't leave anything alone.... but this JK is new to me and I'm trying to find out what I "need" to keep and just how wild can I go? what kind of back pressure does this 3.8 need to still get decent mileage as I realize lift and tires will decrease it some I'm sure..
I have has three different exhaust and I love my current dynomax with the VTT valve and its a 3 inch
