as far as what I got on my car I have a Injen short ram intake, Magnaflow cat back, TLS front strut bar, TLS rear sway bar, MDX steering wheel I havent decided if I want to get a header or not because most people say you dont get that much from adding the header future plans are H&R sport springs and some 17" wheels but I have to say out of everything that I did to my car so far the TLS rear sway bar is by far the best bang for the buck as well as the TLS strut bar both are direct replacements and are cheap.
