A week ago my roomate got in an accident on the 805. Thank God he's okay but his car was a total loss(last car was a camaro RS). Anyways he comes back today with a Mustang. His Mustang is a V6 yr '00 but it has this badge on the back that read "EFI". He tells me that it's not a normal V6 stang and that it has some extra "stuff" done to it. It looks like any other mustang except that it does have dual exhaust and does sound pretty deep when he revs(prob exhaust)? I took a look underneath his hood and don't see anything different. I don't know much about domestic cars and wanted to know if anyone could enlighten me on this paticular model bcuz he wants to see how it handles againt my eshift IS.
