apparently hes running exhaust and some other mods..i'll add shes also running my 3 inch o2 housing for the SRT4. I just learned that today because i call her every now and then to see how things are progressing and to get feedback on some ideas of mine. She just happened to mention that it was given to her a gift by a local. So the car is running a full 3 inch setup from the turbo to each tip.
