Pretty much like the title says, Ive been on these forums for the past couple years just trying to gather as much info as I can on the car before doing any mods. I have ti-msp and love it more and more everyday. I finally gathered most of the parts i want to mod the car with: AEM a/f gauge, tru-boost gauge and oil pressure gauge, FMIC, RDV bypass valve, AWR motor mounts and SSAFC, thinking about an exhaust just not sure if I NEED to get one.
