Hey guys,
I own a 06 4.4i that i have totally altered on the outside. she began as a pedestrian jet black 4.4i with all packages BUT sport, meaning chrome window trim, black lower grilles, and 18in wheels
now shes a totally different beast as you can see from these pics, as well as others i have posted before on this site.

shes got 70k miles on her and just ran out of CPO warranty. My BMW dealer here in NoVa sold me on an aftermarket warranty that will take me until about 120k miles, meaning Ill have the beast for a couple years at least. Under the warranty contract, performance modifications can only be made by a BMW dealer (so only Dinan for me). It just also happens the dealer i bought the warranty from is an authorized Dinan dealer/installer.
Now that I have completed my project on the outside, I am definitely looking to upgrade performance, and am thinking about exhaust, CAI, and ECU. Anyone done any of these Dinan mods to their post facelift 4.4 and have two cents

?
Input is greatly appreciated
