I have a 2000 GT, 5spd. Only mods i have so far are 3:73, short throw shifter, and Ford racing intake manifold. I'm trying to figure out what the best bolt-on mod would be for power/acceleration for 2500-3500 RPM. Other mods i was debating were cold air intake, throttle body, and exhaust; i know exhaust doesn't do a whole lot for acceleration. Any input would be appreciated. Thanks in advance.
