07 EL .... Mods
 

My wife and i just bought a 07 Expedition EL .... It will be her DD id like to do few simple mods for helping in mainly MPG and maybe lil extra HP . I was just thinking a coldair , An E Fan kit , and a full better flowing exhaust NOW tho exhaust cant be loud she wont go for that lol !! Anyone got any input on What exhaust there running or what coldair kits they have used and been happy with . Kinda new here done some searches but really didnt come up with much ! thanx guys

Anyone running gibson exhaust ? Ive ran magnaflow and flowmaster all before on other vehicle's ive owned . I was always happy with sound and performance but this is the wifes so has to be reasonably quite lol

I've heard that the Gibson is the quietest aftermarket exhaust.
